On the one hand this is pretty awesome - just as I expect from the rethinkdb team - but on the other hand I'm wondering that while they are removing serious pain points from web development where are the startups that use these as a competitive advantage? Is RethinkDB understood?
The push functionality is new to RethinkDB and is just coming out hot off the presses. We'll see soon if people understand the advantages, but the initial feedback has been extremely positive.
