A sinatra based, OAuth using list manager for twitter.
I wrote it after someone mentioned being annoyed because they couldn't add multiple people to lists at once.
It allows you to add and remove members from lists, and to create and destroy lists.
Essentially all the things you can do from twitter anyway, but you add users by typing a bunch of screen names into a text area, which is pretty neat.
It uses twitter_oauth and is geared toward heroku deployment–see twitter-list-manager.heroku.com/
It needs three environment variables set to work
And for google analytics(cool rack middleware by the way)
