Tagsie lets users quickly tag many of their friends in one photo. Clever users can use Tagsie on five photos to exploit the design of the new Facebook profiles and plaster banners on their friends' profiles.
Facebook should change the way photos are chosen for the new profile. Users should opt-in to what is on their profile; users should not have to opt-out. There should be a way to keep others from posting vulgar things on my profile. Worst, users who haven't chosen to see the new profiles may still have banners hanging on their profile without ever knowing.
After my room mate and I built this I was able to hang "STEVE" across the profiles of all my friends. Friends who shared my name were pleased.
