Not sure if you'd be into this but we've been using it pretty extensively. So I thought I'd get your thoughts on it.
Adds bin/twitter-cli and interactive console
Nice work on this but I'm not sure this is right for inclusion in this library. I'd love to see it released as a standalone client that depends on the twitter gem. This is precisely what I've done with t (see the History section of the README). Keeping it as a separate project will also make it easier for you to maintain the code and add features over time.
