Re: Losses why?
At first I thought you were trying to be ironic but then I realised that you really don't seems to get it. Explains some of your other posts perhaps.
Groupon's model is because its business model involves encouraging the customers of its customers to be disloyal. It's hardly surprising that this makes it hard to keep customers which means it needs continually new customers which is acquires not from the internet but from a good old-fashioned sales force. It's closer to Tupperware or Avon than it is to an internet-based service or even classic voucher services which seek to spread the cost of promotion between manufacturers and retailers. It doesn't scale well which is why its expansion has just led to higher costs. This might be okay if it had a business model that wasn't so parasitic. Other businesses with similar requirements (people on the ground) are doing better either because they cover new markets (AirBnB) or improve yields (Opentable). Maybe the "pull" approach as has legs.
