The short answer is I, and I'm sure tons of other people, do not need another way to talk to each other, we're doing just fine. There have been so many offering with almost that exact wording that its become a cliche.
> do not need another way to talk to each other, we're doing just fine
People are very poor judges in deciding whether they need something new before they actually see it. I have no idea if this is something we "need" but this is some bizarre anti-progress attitude. The world is in need of new and better ways of doing almost everything.
I'm also challenging that "we're doing just fine". Progress is always welcome and needed.
That said, I'd disagree with zavulon on Branch slogan. It's fun and provocative, and its vagueness kind of invites you to try the service. Which might be a bad idea for a startup—but as the rest of the ‘book cover’ looks very nice, I think it'll work.

One could argue that people in general aren't good at judging if they actually need something or not, regardless of whether they saw or used said thing.
