This unofficial Python library is for use with the Twitter API. The library includes a command-line tool that allows one to receive and send tweets through an IRC bot and access several types of twitter data. The Command-line Tool allows users to view their tweets, follow/unfollow friends, and view the public timeline. In addition, the twitter-log command will send all your tweets to a simple text file. The twitter-archive and twitter-follow commands will log all the tweets ever sent by a user and all the followers a user has, respectively. Extensive documentation and code examples are available at the project website.
With a domain like map.pr, you'd think this would be another link shortener. Instead, it uses the Foursquare API to give you a great way to visualize popular places on FourSquare. And, if you're following the World Cup, you can also use Mappr to find spots frequented by fellow fans.
