I can't agree more roadkill.

I don't think they will lose interest quickly, but it will be over time. They will 100% come back and keep updated on their favourite celebrities, heart the comments and such. But if they keep getting their requests unaswered, then definitely, they will move on.

However, for the ones who get their requests answered, they will show their friends on their twitter/facebook page, and they tell 10 of their friends and so on.

I do believe in management and they will find a way to engage users. The video integration will be very interesting.
