Hats off to M.G. Siegler for noticing this:

Yes, Rubin for some reason has deleted his most famous tweet. His first tweet! One that led to stories by myself and others.

That tweet no longer exists. His first one listed is now from December 2010, trumpeting, what else: Android activations!!!!

Where did the initial tweet go? Who knows. But it sure looks like he deleted it. Deleted it in an “open” way, I’m sure.

UPDATE: Looks like it was a mistake on the part of Twitter.
