TweetAtCongress is an API that provides information about Congress members on Twitter.
The idea behind TweetAtCongress is simple—by using the API on your Web site, you can give users a way to look up and tweet at their legislators. As more and more legislators realize that social media can be a powerful tool for engaging their constituents, public advocacy groups, too, should harnass the potential of sites like Twitter to give their supporters a new, easy way to express their point of view to their elected officials.
TweetAtCongress was created by Noah Cooper, a Web developer and online advocacy enthusiast from Austin, Texas.
