Stack Overflow is so successful because hardcore programmers and IT professionals ask and answer hard challenging questions that are interesting to their community.
If someone came in and asked a stupid user support question like "Why is my Computer running so slow?" it would be closed in less than 10 minutes.
We need the type of questions that are asked on WP Hackers Mailing List not the kind that are asked on The WordPress.org How to and Troubleshooting Forum. WP.org has a dedicated group of moderators and volunteers who answer the same questions over and over from users who never come back or even mark their topic as resolved.
Most professional WordPress developers, designers and webmasters don't use the forums because of the enormous amount of questions similar to the ones get every day from clients or friends. Most real questions there are answered with a link to the Codex.
If we want to continue to attract users who are passionate about WordPress and care about the how and why then we need to make sure that we don't ever become a "Yahoo Answers for Wordpress" then we need to make sure that crappy questions like I need a plugin in wordpress like google tasks are closed and removed.
I don't want to discourage new users from asking questions but I want them to put a little effort in the question if I am going to put effort in to the answer.
We only have 9 users with enough "power" to vote to close 6 who can edit and 3 who can delete after close.
We should lower the requirement needed to vote to close and comment more on the users who continually ask bad questions and never accept an answer.
If you see a bad question take a few minutes to comment it on it or vote to close if feel like it doesn't provide value to all the other users.
