"I’ve found that while I’ve moved on from the Rails scene, the scene has not moved on from me"
The true quality of a community is not just a measure of how forceful or big it is, but how easily it can adapt to change. This quote, plus the fact that the plan for "moving forward" was to pull in another framework wholesale, does not bode well for the Rails community. It by no means indicates that the Rails community is doomed, but it does not bode well.
I'd also like to take this moment to point out that this is yet another indication that the Ruby community != the Rails community. Quite to the contrary, I think you'll find the Ruby community quite flexible and robust when faced with opposition. (Just read some of the recent ruby-talk discussions on 1.8.6 vs. 1.8.7 if you don't believe me...)
