This is simply awesome. Â Facebook launches a new API using OAuth2, making it much easier to integrate with Facebook from your Rails app, and Michael Bleigh quickly churns out a new oauth2 gem.
Having dealt with the pain of Facebook integrations recently, and having really enjoyed using OAuth, I had to dive in. The result is a new Rails Kit! :) The Facebook API Rails Kit gives you a sample Rails app that integrates with Facebook and shows you how to post to a Facebook user's stream. Check it out -- I think you'll like it. I would have loved to have had this a few months ago. :)
