A lot of people have a bunch of presumptions about RT but have never used it, so they wouldn't know the benefits of it. They just go by "what it sounds like". It's new technology, so people are justifiably wary.
As for g wave. Yes, i'm aware. This hasn't been done in an app however, so thats #1. And #2, we introduced a unique "beam in" mechanic that allows people to actually respond, comment (interrupt even) on point, as far as I'm aware, noone was able to solve this problem, of 2 people talking at same time, before (solve it well that is).
