The majority of questions are answered by say the top 200-500 users disproportionately more so as you get closer to Jon Skeet :). Now while the ratio of "askers" to "answerers" is expected to favour "askers" I have to wonder if this has perhaps gone too far. It's at least raising as an issue to talk about I think.
I started answering jQuery questions late last year. At the time there were quite a few of them, lots of simple ones and not all that many people answering them. This was useful to me as I used it to help learn jQuery. Real-world problems from programmers beat made-up problems from books, particularly in a forum where others will vote you up or down if you're right or wrong.
I'm not sure if it would be possible for someone to do that now. jQuery questions get jumped on like a feeding frenzy. It's not the only tag like that either. Between Jon Skeet, Marc Gravell and others, it'd be damned near impossible to get an answer in on any C# question unless you instantly know the answer and are lucky enough to see it first.
Now while the efforts of those guys should (rightly) be applauded I have to wonder at the long term effects. To borrow an analogy, it's like a handful of predators have been so successful in this ecosystem that they've crowded out every other predator to the point of near-extinction.
This is one of those "where is the next generation coming from?" scenarios.
Anyway I'm not saying it is a problem. Nor am I making a suggestion how to fix it if it needs fixing but I am curious to hear some other opinions on it.
