Hmm...this is first i heard of it. I just saw on my aapl news saying they will do apple and android apps. I went on to check out the site. I can totally see how this could easily crush groupon and the likes. Man, if this came to my town, i would be using it.
They are still only in a select few cities it seems. And so i could see much potential for growth. I am a little sketchy, but would hate to look back in 3 yrs when its at $50 and think i knew about it and didnt act.

Guess at the very least it is going on my watch list to be monitored and have some more investigating done on them.
