My personal opinion is that you don't need to be that different in terms of functionality if you can make a difference in execution, which I think they're doing in terms of user interface and hopefully with marketing in general.
More broadly speaking I'm interested in how they plan to go to market beyond the "echo chamber". Some of that they're probably keeping under their hats but I'm keen to find out.
