Nah it's alive and well. The commons is about to transition to a new location which I think will be good. Also Rob from Bitcoin Park is taking over to call it Bitcoin Park Austin. I'm not sure if plenlab will be rolled in or not. I imagine that will be very successful regardless.

There's also a lesser known, but very cool, cypherpunk hacker space in town called Lab484. It's a new project, but dedicated to a full open source stack including creating a new way to gain internet access without ISPs. I will be interested to see how they do over the next few years.
