What is your opinion on Sinatra's support community? I keep peeking at Sinatra for my new app. I have a Merb app in production and working on a new one. My new app has characteristics quite different than my old one but I still get to borrow my education from Merb. Unfortunately, Merb's google group is a ghost town these days. I worry this is going to get worse and have no interest in counting on Rails 3 being useful to me in the next year.
