I'm trying to decide which Ruby web application framework to use (if 
any) for a new project. To that end, I'm looking for all Ruby web 
application frameworks that are out there. Following is what I have so far.

Am I missing any major contenders?
Has anyone actually used any of these on a full project? If so, what was 
your experience with it? (Flexibility? Ease of learning? Ease of use?)
