We're have lots of ideas for Raplets which would be useful, and talking to lots of people. But anyone can write a Raplet!
Just to give one example, http://favstar.fm should be coming soon, letting you see the person's most-favourited tweets :)
Ok, possibly a dumb question but how do people write raplets? The TNW article doesn't point anywhere and I can't see anything on the rapportive site either. What do people need to do?
Please contact support@rapportive.com and we'll send the documentation. For now we want to work closely with developers to make sure we're heading in the right direction.
