Do you think we could engage with this new subreddit?
http://www.reddit.com/r/improvingwikipedia/
by "improving", it appears to be specifically focused on content creation rather than any sort of structural changes. Nothing that couldn't be done on-wiki, of course, but for whatever reason (familiarity?) they've chosen to do it here.
Note reddit has had http://www.reddit.com/r/wikipedia for quite some time - it has 150,000 readers, but it is (mostly) just a place for posting links to interesting Wikipedia articles. The new one only has 36 readers... but it is less than 24 hours old!
