Hi there,

This has now been implemented as “Twibutes”. As each milestone of supporters is reached, a new Twibute is created in the form of a collage of all the profile pictures sporting your Twibbon. The key milestones are 50, 100, 250, 500, 1000, 2500,5000,10000,15000,20000 and a Tweet will be sent out accordingly

Thanks,

The Twibbon Team
