Does DailyBurn really work?

I’ve been researching on weight loss fitness programs, and I find dailyburn to be interesting as it seems to work like a social community. I have read reviews, but I haven’t found anybody claiming they have lost any weight using it; usually, you can find before and after photos of people who have successfully completed any fitness program, but I haven’t found any other than the ones in the commercial.
Does any of you or anyone you know have tried dailyburn? and if so, what were the results? and, how long did it take to see results?
