Ive been using Viggle since January got a total of $310 worth of Amazon gift cards.
Viggle has changed alot since they launched in Jan. Started with 2 points per minute(now 1 point per minute), Viggle Live 25-200 points for each correct or incorrect(now 1-10 for correct or incorrect). Amazon had $5 gift cards for 2000 points now $25 gift cards for 62500 points. They added alot of Audio able check in channels since Jan. alot after the DirecTV deal. You can't manualy check into shows 1 hour or more(unless they are sports but not PPV Sports like WWE, TNA, UFC). They now have a limit of points you can get a day 6000(TV points, bonus points, ad points, etc.) and a time limit 720 minutes/12 Hours) in 24 hours you can get points for watching TV.
But I love the App, free money just for watching TV! So far the DirecTV bonus points have been for watching HBO/Showtime TV Series or Movies on the weekend(Boss, Weeds, a movie), & checking into a Sunday Ticket game. Hopefully like DirecTV does with GetGlue & Miso, I hope Viggle will have a app right on the DirecTV box where we can check into what we are watching w/o having to audio check in
