overview

stackexchange has built up a very sophisticated web-based, public, auto-archived chat system (FAQ). for new “se” users, it requires 20 rep pts earned across any se sites to participate in any chat room. that rep score is obtainable from eg 4 question upvotes or 2 answer upvotes.

the chat has very nice formatting features such as hyperlinking, different fonts, inlining (images, se Q/A, wikipedia articles, amazon books, tweets) easily accessed user profiles, and there is even a way to display latex formatting (MathJax), and although while somewhat familiar to those who use wikis, it can take some learning to master the syntax. the chat rooms are largely underutilized in general with significant potential eg for scientific uses eg polymath-like and open science projects.

outside of a few highly active chat rooms, they tend to be dormant for long periods and have occasional rapid bursts of activity. se also has a mechanism where inactive rooms are “frozen” after 2wk. there is a “sandbox” for learning/ experimenting with the chat features.

it is easy for users to create their own chat rooms for miscellaneous purposes, “invite” other arbitrary users, and moderators generally take a very hands-off, even near laissaiz faire attitude with some exceptions. no direct reputation score changes are involved in chat although indirect routes are possible (eg chat users notice specific Q/A identified in chat & act/ vote on it).

the web-based concept of chat is not quite like other cyber chats because with the se mechanisms, they can be used for extended dialogues lasting over hours, days, weeks, or even months in some cases. these can lead to and support either very synchronous or asynchronous type dialogs. either multiple users (resembling nonlinear brainstorming sessions verging on parties) or 1-1 exchanges.

there are occasional planned/ advertised/ announced chat meetings.

pseudonymity is allowed. users can reveal as much or as little of their backgrounds as they wish. despite some criticism and/ or minor unfamiliarity, “its a [privacy] feature, not a bug.”

therefore overall the architecture is uniquely suited to all kinds of conversations and dialog from the trivial to the momentous. (eg even topics that can trigger major commotion or are verbotten elsewhere on se, eg amateur results/ papers, P vs NP proofs, etc, wink!)

it also works for certain informal types of questions/ topics that may be highly frowned on as “official” se Q/A such as what areas of CS are of special interest (aka “hot”) to participants eg for projects or research. or eg, say CS in pop culture, like movies, tv, cartoons, etc. there are even occasional flashes/ glimpses of advisor/ student interchanges except in an informal/ casual way. also captures misc very revealing “behind the scenes” se dynamics such as mod decisionmaking/ chatter.

via participation here, my ultimate dream is to build up substantial attacks on significant open problems or even advance research programs in the field via all these elements, harnessing collaborative team dynamics and open science approaches. despite the sheer ambition of that ulterior agenda, one can occasionally see brief glimpses/ flashes of it in play, realized.

theres really nothing quite like it anywhere in cyberspace! se chat rooms combine the informality of cyber chat with highly educated, dedicated, intelligent participants which can be disorienting at times and seriously empowering at others.

since early ~2013 have had many engaging and sometimes fascinating dialogs. its also useful for participating in extended discussions of papers or blog pages with unusually enthusiastic commenters. here are some highlights. (see also volunteer).

an outstanding recent movie portraying the game-changing aspects possible of chat, see Fifth estate profiling Wikileaks/ Assange, starring Cummerbatch (who seems now to have definitive cyber/ geek tastes/ inclinations!)

another neat and meticulously researched book outlining the significant/ major possibilities and influence of an informal scientific study group, see How the hippies saved physics by Kaiser (official site with interviews etc).

stackexchange profile tips

• fill out stackexchange profile. ofc stackexchange does not require divulging any personal information and one can avoid any areas one personally does not wish to share, but too much secrecy can get in the way of a chat, which is open and better based on details.
• most people do not and it means its more like random strangers meeting (with all the awkward silence). the more details in the profile, the more others can talk to you about your own interests and avoid asking the same typical questions (eg what someone might ask you anyway on approaching you at a party etc).
• try to list something different/ special about you that others might remark on or you might like to chat about
• give geographic location, more specific the better. europe, US, state. others can relate to you on that if they live nearby, but even those that live far away may have some better picture of your local environment or even culture etc.
• if at a school, please name it. please indicate your year. this helps to tune the communication. eg a university senior has a different situation/ outlook than a freshman etc.
• did you do any postgraduate work? please list it. if you have a masters degree or Phd please name/ cite the thesis online if possible. these are public information anyway.
• what is your job?
• do you work on any projects outside of work?
• for technical/ scientific chat rooms, try to describe anything youre particularly adept or even expert at.
• not many people have blogs, but even a small blog, intermittently/ infrequently updated can tell others a lot about you and your interests. there is absolutely no shame in a sparse blog with only a few entries. all blogs are “works in progress”. please cite it on your profile. please cite any links that are related to your interests or personal life. eg clubs, topics, etc
• do you have any agenda in joining the site, any particular motivation, any personal area of focus?

cool chatting session tips

• when you show up in chat, try to help carry the conversation, if you know what that means. long pauses distract from the flow. imagine talking on the telephone and the other end goes silent. that happens on chat all the time.
• maybe somewhat surprisingly/ uniquely, on stackexchange chats, it is not necessary to have a synchronous conversation, it can be asynchronous ie people write back and forth over different periods. however for this type of chat, one must write a little more than single lines and try to anticipate the flow of conversation more and freely/ proactively volunteer more info.
• if someone asks you specific questions, or more than 1, ofc youre not obligated to respond but try to specifically answer them, each of them. try not to be evasive and avoid/ ignore questions/ interest. if you dont want to answer, maybe say why not if possible.
• favorite popular media, recent room related events/ news or people related to the topic can be a chat focus. also something to put in profile. eg movies, books, tv shows, celebrities, etc
• everyone is a volunteer. dont be demanding or impatient. nobody is required to help you or pay any attention. the main site has a specific purpose of answering questions but chat rooms are freeform and there is no such expectation or default. stackexchange users tend to be very helpful in general but some people are there just to have fun, “blow off steam”, procrastinate from their “real” jobs, etc. be appreciative of any help you receive, no uptight attitude etc
• if you have to leave, and youve been talking awhile, its polite to say so rather than just disappearing.
• scan recent or even older chat transcripts to see what people are talking about, and respond if you have something to say/ add. dont feel like you missed the conversation. the conversation on certain topics may be evolving/ ongoing, sometimes goes over hours, days, weeks, or even months.
• familiarize yourself and use the chat reply feature as much as possible esp when reraising prior topics. you can also quote prior chat messages. and the message starring is a nice feature but please dont gratuitously star stuff that doesnt deserve it.
• try to visit at least intermittently and say something, anything!
• a sad/ regretful situation is someone who was once very lively/ engaged in chat (or stackexchange in general), but then stopped visiting entirely, not even rarely. they may be missed by more than one, or many. try to be flexible/ openminded/ friendly as possible. those that permanently leave may have personality conflicts with regulars, unresolvable complaints, endless grudges, etc.
• if you have a longrunning conversation with 1 or more people you can create a separate chat room and invite all your cyberfriends. these are uncommonly created but maybe some regulars might wish that some longrunning conversations might go on elsewhere esp those unrelated to the general room topic/ focus.
• links, links, links! leverage/ maximize cyberspace to your advantage. use oneboxing feature. SE Q/A are automatically oneboxed. please be as specific as possible. if you talk about a book, name it along with the author, give a section or page, better yet a link to Amazon or the toc somewhere on the web, etc., if you go to a university youre talking about include a link, etc; youtube videos, papers/ PDFs etc
• you might think that chatting is time consuming, or verging on a waste of time at times, and it can be, but it doesnt have to be, and can be far more. chat is what you make it. there are some highly intelligent/ accomplished participants, and even more may show up in the middle of lively sessions. dont assume that people there dont have another major life/ responsibilities/ job etc going on. ofc a long conversation takes time (and thats part of the unique pleasure), but continuing/ adding to a thread of conversation can take only a few minutes a day.
• pay particular attention to regulars, site moderators and room owners, and give them some respect esp about preferences/ good boundaries of discussion. definitely avoid testing/ pushing their boundaries. some of them have “seen it all” and have to deal with unruly users, and certainly dont need any more of that, and may quite justifiably have little time or patience for it. have some sensitivity and emotional intelligence.

near misses

😳 😥 😡 have some personal agendas on research/ collaboration etc and have discussed these at length with many of the above. however, there are certain “near misses” that are even a bit )( excruciating. these are for me tantalizing/ elusive/ … therefore ultimately frustrating conversations on key topics that end up… going nowhere. at least in the moment/ for now. they are exactly what have been fantasizing about for many years, and then disappear, poof! alas! lol! maybe a bit more typical of younger users with grand ambitions and shorter attn spans, or maybe many competing items/ interests/ priorities 😀 😎
