I was recently wondering out loud to Patrick over IM about there being an easy way to check if my installed Gems are supported by Ruby 1.9. A quick Google search didn't turn anything up so after a little prompting I wrote Am I Ruby 1.9?.

Am I Ruby 1.9? looks at the 5 most recent comments on Is it Ruby 1.9 for each gem you have installed and then guesses whether it works. Hopefully this will help spark some interest in people updating gems to support Ruby 1.9. I know there are a few I'm going to take a look at!

Is It Ruby 1.9 is a great project, but like all social constructs, it only works if people participate.
