I don't know a lot about the use case, and there are certainly downsides with Rails on JRuby. One use case for JRuby is when you've got a large, long lived project and want to clearly define an API that a bunch of devs are going to work on by putting richer type information around some core classes - whether in Java or a lower ceremony option like Scala. It's also interesting if you want (for example) some Clojure code (although I'm not too sure how seamless the interop would be). I know about using proper testing to replace the "nanny compiler", and personally I'm almost always working in a dynamically typed language, but I do find use cases where static typing and all of the formality and tooling support it brings can add value. That said, I'm not sure a Rails app munging RSS feeds is necessarily that use case . . . I have heard some credible people recommend JRuby for running Rails apps from a performance perspective. Any particular take on that (other than don't pre-optimize by worrying about performance?!). I'm still very new to the Rails world although for the small projects I'm currently playing with in Rails I'm just throwing them up on Heroku.
