I'm imagining that I see proportionally more "bad" questions on SO. They continue to be closed, but I'm wondering if a problem looms.
We all know that the comment model of a blog breaks down as the community grows. It seems to me that the current model of all-questions-are-on-the-front-page may have similar limitations.
To be specific, I enjoy browsing the current questions, but I enjoy it less when 1/4 of them are "What's the best language for a beginner?" even if such questions are closed. At some point, the experts we depend on will be driven away by the incredible bulk of new users.
I have no proposed solutions, since SO has depended heavily on accessibility to new users. I'm just curious if this seems like a future challenge to others.
**Addendum: ** Please don't interpret my question as elitist, or anti-newbie. I am (more-or-less) a newbie, and as I was changing vocations I was greatly blessed by the easy, free, fast, and friendly help I received at SO. I'm not saying that new people shouldn't be welcome, or that stupid questions belong elsewhere.
Nevertheless a certain proportion will need to be maintained to avoid what happens on a blog when the comments under a post number in the hundreds. At some point, the conversation breaks down.
This may never be a problem. But it might.
