Here's a sneak peek at the personal representative page for users. Capitol Bells will match the number of votes you and your Member agree on and displays it as a vote score. While you're checking that out, you can call your Member right from the app, or just tweet him or catch up on Facebook.
One thing I am excited about is the Rep page's Twitter stream. It displays the most current tweets from your Representative. Right below it shows the most current tweets sent to your Rep using the hashtag of your district, for instance #TX06 for Texas's 6th Congressional District.
