Previously, I’ve mentioned that I’ve written a script that will show a Twitter user who they and another Twitter user both follow.

Well, a script isn’t much use to me or anyone else: you can’t run a script on an iPhone. So like all software wants to be, this script is now a simple little web application: mutual. Please be gentle, and I know I’m not a designer.

This should be the start of more useful little applications like this appearing. I’ll blog about that. Also, for the programmers out there, this is written using the Sinatra Ruby web application framework. If you thought writing apps using Rails was fast, well, you ain’t seen nothing til you’ve seen Ol’ Blue Eyes take the stage.
