Wow! Pretty cool this has gotten some attention. A bit of background - our team has had BLOCKS in the works for a long time, and in fact it was part of our founders' initial pitch to investors. We've been actively developing and testing BLOCKS for about a year, and over 800 companies signed up for early access. If you're a developer doing something that is "realtime" - collaboration, notifications, device signaling, etc - then I'd encourage you to give it a try.
