I'm happy that there's so many WordPress plugs but often I feel like we brag about the numbers without considering that half of them are dead and many more are outdated. I'm so very tired of wading through old plugins that aren't even compatible with WP3.0.
I know this month is meta-cleanup month so I propose that we add a control to plugin search on wordpress.org and in wordpress' native interface to constrain a search by compatibility with a particular wordpress version.
It seems like the kind of job computer would be good at, matching and sorting by numbers. I strongly propose this mostly for plugins but also for the theme pages.
