ha I never bought into that whole "invites are spam" bit. Generally people like apps and invites. But its hard to believe that because the minority is very vocal.
If you wanna chat over email I wouldn't mind sharing some tips.
Invites are not spam by themselves, but they're abused by many apps in a way that makes them spam. And you're very wrong if you think the silent majority enjoyed the FB spam fest a while back.
Abusing invites with more "viral channels" will only get the app into a lower invite threshold. FWIW I think a free TV is a pretty good incentive and will have people choosing the friends most likely to use the app. I do agree on promoting more the contest and the free tv thing, people tend to not read anything without flashy colors and big fonts.
