So sorry to hear about this. Of course, I didn't pay them anything for those intros (and I would have, btw) but I imagine that in general has something to do with their decision to close up shop.
I'd be interested to learn a few things: 1. What was the story behind their (hoped?) business model, and why did they decide to close the doors? 2. I wonder if someone will pick up the mantle where they left off -- perhaps not at the same scale -- but there is absolutely a need for this sort of coworking directory.
Perhaps a side-project-in-waiting for someone...?
