From the discussion here, it sounds like:
1. futuremint was developing a bunch of Rails applications in Rails 2 + Ruby 1.8.x.
2. futuremint got bored of coding in Rails, was tired of Ruby being slow, and yearned for an IDE.
3. futuremint checked out Smalltalk/Seaside and Common Lisp. He liked it for a while (for reasons that seem unclear). There doesn't seem to be much discussion of continuations (which seem most salient to me as an outsider, but who knows!). Refactoring in Smalltalk is easier (which isn't surprising given that it's a really simple language).
4. futuremint returns to Rails 3, Ruby 1.9. Things are faster, he uses an IDE, and he is content with his ability to meta-program even if the syntax is ugly. futuremint is tired of lots of boilerplate and conventions because Smalltalk is so small, and he's tired of not having a community like Ruby/Rails in either Smalltalk/Seaside or Common Lisp.
