I agree. I'm a 37s fanboy. Web tech has made a quantum leap in the last year. The difference between rails 3.1 and rails 2.8 is huge. Not to mention html5, css3 and new javascript libraries such as backbone-js. These are game changers. Adapting them means a rewrite.

There's no Rails 2.8, I guess you meant Rails 2.3...

There are three major versions of Rails that are still maintained: 2.3.n, 3.0.y, and 3.1.x
