What's the best way to keep up with what's going on with Rails 3? I've been reading your articles, and wycats', and I'm subscribed to rails-core. But when I tried to make an app yesterday, the most basic hello world app with one scaffolding didn't work. I posted to rails-talk yesterday, and nobody answered... any thoughts on this? I'd like to keep a little bit ahead of the curve, and possibly contribute if there's still low-hanging fruit...<p>EDIT: And it's not like I expect anything to work in a prerelease either. But I couldn't find anything directly on Lighthouse, but I don't know if that was because I was searching for the wrong terms, or if this is being worked on by someone, or any other number of things...
