While I am excited at the possibility of ditching Gmail, one of the main things I am most excited about is that DHH has been hinting at a lot of new tech to come out of this including what he mentioned as the simplicity of Rails for the front end world.

I've tried taking a look through the sourcemaps for app.hey.com to get a feel for how that might be working and saw some interesting stuff in there around HTTP/2 frames and their Turbolinks approach but am going to have to wait until someone more competent is able to spell it out for me.
