This is an interesting concept for a social game site, even if I am not so sure what its business model is.
Being the first person to have just won something on it I feel I owe them a plug in (I have no stakes in it, just happy to have won, trying to give back).
The site has its quirks and it is still in beta, there is loads of work to be done on it to get some traction.
Improvements to the UX are being made all the time, would you have any suggestions as to what they could do better?
The site url: http://begfor.it
Could be an interesting marketing exercise, though. Even if you don't receive the product in question, you may end up wanting to buy one for yourself anyway.
Also, the 4-step diagram showing people 'how it works' has two steps saying how one signs up, one saying 'Beg & Vote' and then 'WINNING!'. It doesn't explain that well what the site's actually about. Something like "Tell us why you should get this prize","Vote for other users", "Win!" could work better.
Or I might be wrong. I guess feedback is (usually) better than silence, so there you go. :)
EDIT: Aesthetically, the site looks really nice. The scrolling sidebar's annoying, though. Using the scrollwheel or scrollbar makes it lag behind. It distracts from the items on show, which should probably be the focus of the user's attention.
