I've been thinking about this lately too. I think it could be beneficial to have something like the co-founder wish list (spreadsheet) where people can post easy tasks they don't have time or skills to tackle (test this app on android, take inline CSS and consolidate it, add Ajax, document this etc). Maybe a twitter hashtag too. Put it together and link to Github through their API. Issues in Github can have labels, so maybe if you submit a repo to the site and have issues labelled (easy) they get pulled in and people can pick off issues they could help with.
Ultimately, of course, this doesn't solve your problem. However, it would address the issue nicely since this question is asked repeatedly in many places around the web.
