Number two player in the social voting space Reddit has won by a clear mile in the April Fools Day prank competition by rebranding the site as Reddigg.

The skin includes the choice to Digg an entry, or bury it, vs the usual vote up or down on Reddit. Unlike Digg, Reddit offers a transparent voting system; the inclusion of a bury button up front is pure mokery.

A close second is Google, who worked off the theme of the Cognitive Autoheuristic Distributed-Intelligence Entity, with sub pranks outside of the original prank.
