Kevin Rose also left Digg at some point, not sure how much of that demise is on him. He had to buy it back for this second run.

The interesting thing about Tidal is that is was originally owned by artists (Jay-Z, Beyoncé; Kanye West; Madonna; Jason Aldean; Alicia Keys; Arcade Fire; Coldplay’s Chris Martin; Rihanna; and deadmau5) Who have since sold off a majority share to Block, while Jay-Z kept a board seat and other artists still have shares. Curious if it will last.
