In the google plus demo thing, by default, you could autofill the ID with someone famous like Robert Scoble .. For people like me who are not active on G+ (thats pretty much everyone)
Certainly be adding some examples though, but here's mine for now http://qiip.me/edlea
In a user perspective, "Try Now" or the "See Demo" is the first button I press before reading anything.
I think you need to tweak a little bit of that workflow. Otherwise, great app!
On the homepage, you could have a conveyor belt like imagery where twitter, facebook and G+ icons come out as a "qiip". Below that you could have buttons like "See example" and "Signup" etc etc.
Cool project, by the way.
Shoot him an email and ask. Probably he's gonna love it.
