My first impulse was to simply say that both the question and the accepted answer seemed plain childish, very in tune with the competitive spirit fostered by many here. But I'd wouldn't be posting if that was the only thing I had to say... Were that the case, noone would have time to answer all web comments that gives them such impression.
I'm posting only for saying actually why, for me, sites like LQ still exist, and will continue to do so regardless of how ultra cool and efficient and < insert fan adjective here > may be Stack Overflow:
They are intrinsically different in their aims, and that reflects on their atmosphere, communities and of course this includes their interface and, well basically they just are very different. They aren't really the same type of beast (like perhaps Experts Exchange is, and in that regard Stack Exchange is indeed an advancement).
SO: the rep system is central to the site, there are many things you can't do unless you gain points. The atmosphere is more competitive, because more users regard reputation as a main objective, many are constantly "policing" other's posts, and many are stalking questions. Its common to perceive the tension, especially between young people (yeah most older folks don't give a flock about the whole thing, actually, they only like nice content).
LQ: the rep system was added many years after it emerged, and it's accessory. All normal users (ie, not moderators/administrators) can do an awful lot more without more points. The extra points needed for, say, private messaging are only to detect truly regulars and keep away trolls. But not because other reasons. The atmosphere is far more relaxed, less competitive and that reinforces a sense of comradeship.
SO: open discussions are discouraged.
LQ: open discussions are not only encouraged, they are basically a thread's life. This site encourages comment exchanging. Threads are frequently open-ended, and can contain offtopic content.
SO: the main objective in a thread is to answer a question, get the best answer, and if possible try to get it fast too. Things in this regard Have to be Perfect TM.
LQ: people there won't always solve upfront a question, instead embarking on the aforementioned dialog with the OP and with others participating. The question may get answered many posts after the thread start (see above), or never, or could be just a question posted explicitly for open discussion (see above). Kids wanting to get an exam solved, for example, won't have so much success as in SO.
SO: answers and questions can be forever improved. People can edit other's questions/answers/comments, even delete them or turn them into community wiki.
LQ: you can add posts to an old thread (provided the new content is relevant), and otherwise you can start a new one and mention the previous thread as necessary. Also, aside from people marking a comment as "useful" or "non useful", that's all they can do about others material (except of course mods/admins). A bad post stays in the thread right were it was posted as does a good one too. People can't just submerge into oblivion or downright delete content they don't like.
SO: has the ultimate 3.0 interface, sophisticated editing, and connects to your fridge if you want it (and of course, it has an API!!!!). It's the Mac of the Q&A sites.
LQ: just your old forum style. You have bbcode, the posts and, oh yeah, you can add some images too. It's the Linux of the Q&A sites.
And, ehhh I think you get the picture by now. It's two different views of the world. But it's interesting in which of the two sites the current question and accepted answer has popped up (yeah we're so much better!!! how do they exist yet??? shouldn't they have extinguished along the dinos??).
I'll leave to anyone who wants the task to evaluate if SO can learn anything from LQ. Cheers, and keep up the modding!
