I've decided to have a look around for open source projects that need a hand and lend a bit of time to one or two. One question though, is there a site(s) that lists current open source projects that are looking for developers and is there anywhere I could for example filter open source projects by language/technology/etc.
What I'm after is a way of getting an overview of many open source projects so I can make a decision whether they interest me or not.
Ideas where to find such information?
