OAuth is cool but developing with OAuth can be a pain. Inspired by curl and Hurl.it (featured on Episode 0.1.5 with Leah Culver), the Twitter team has realeased a couple of tools to make developing with the Twitter OAuth API much easier.
sudo gem install twurl
Then from the command line (not the Ruby console) you can authorize twurl using your API keys:
$ twurl authorize --consumer-key the_key
Now you can make requests to API methods:
$ twurl /1/statuses/home_timeline.xml
