Simplest and most concise Twitter OAuth implementation

Way to build a short and beautiful step path to the land of Not Invented Here. It's one think not to write a tutorial to using one of the well supported OAuth gems. But you didn't actually commit to helping people either. If (and when) someone finds a bug in your implementation, they won't be able to fix it with a gem update, they'll just have to return to your gist for the lifetime of their app.<p>On the other hand, you've done a beautiful job at showing how simple OAuth can be. If I ever want to write a twitter client in Io or something, I'll definitely be ripping off your (apparently still copyrighted) code to do it.

Just for fun, I thought I'd round it out by implementing the last two steps of OAuth (sending the user to Twitter and exchanging a PIN for an access token) since somebody else already did all the hard work :D<p><a href="https://gist.github.com/564687/" rel="nofollow">https://gist.github.com/564687/</a>
