Pardon my Ignorance, but who is Andy Gross?
I'd like to know who he was, what he worked on, etc... The tweet is too vague.
And this is not to be consisted a full bio by any means, but here are the highlights. Andy Gross was Co-creator of Riak and Webmachine, Chief Architect @ Basho. Formerly @ Mochi, Apple, Akamai, a noted speaker, and lover of cats.
He worked at Apple and like erlang... sadly, I know little more than this.
Given how small Mochi was then, I bet they knew each other. Just goes to show you the tech world is a really tiny place.
