I am mostly active on ServerFault, but have lurked here on and off. I'm also active on meta.SE and a few other SE sites.
On ServerFault and other SE sites, there are issues with question quality and discussions of what to do about it, so I've read with interest the posts here on meta.EE about whether you're being too harsh in dealing with bad questions.
My impression as (largely) an outsider is that there seems to be a pretty good concensus that bad questions should be swiftly downvoted and/or closed. Based on a fairly look at some statistics for the site and looking at questions over the past several days, it seems to me that it works - the percentage of questions that seem "bad" to me is lower than on, say, ServerFault.
What I'm wondering is what the regulars here think - do you think your method of dealing with bad questions is working? Are you able to keep up with the number of bad questions and shut them down and keep them from swamping the good ones?
