No clue why they got all the attention.. but @mattt has gotten involved in the community here and there. I've run into him a few times at @damon's Friday Night Hacks.

In terms of other startups, we have Other Inbox, Infochimps, WPEngine, and a number of other things that are relatively quiet. In terms of "big" players, we have Facebook, Evernote, Zynga, some of Sony's game dev (DC Universe Online started here), and Ebay/Paypal is moving in. OpsCode and Mozilla both have lead evangelists here too.

And there are probably dozens of things I'm missing..
