Favrd is a web app that lists interesting things that show up on Twitter, based on the number of times an item has been declared a 'favorite. Here's the raison d'etre:

It works on three principles: first, that anyone who wants to can have their vote counted; second, that things people find interesting are more important than people who find things interesting; and third, that by any means necessary, web-strategy, social-media, online-marketing webcocks – unaware as they are of how toxic their presence is in the arenas they cannot shut up about – must and shall be filtered out of view.
