New rating system
There's a lot of talk in the mailing list about rating/voting on articles (as an interface selection, not a purely wiki-social process). I'd expect to see it rolled out within the next month (update, Dec. 4: Wales told the NYTimes it'll be rolled out, most likely, in January), once a good implementation gets worked out.
A good article can become a bit of a mess with just a couple of misguided edits (which, hopefully, get reverted); it'll be interesting to see how the voting system deals with rapidly changing articles.
- Most users don't take time to edit, but many of them would click a vote box.
- Seeing simple numeric ratings at a glance could make deciding how much to trust an article easier, and browsing more fun as you direct your attention away from the chaff.
- A software-compiled list of low rated articles could provide a focus for editors' attention.
Rating articles this way could undermine the social nature of wikipedia. Artifically-created rating systems aren't subject to the caveats and nuance of thought and discussion, nor the incredibly complex and somewhat effortless interplay of human social interaction.
