Yeah, but where's their moat? Contrast to FB -- the value of the network increases as more people are in it. How does groupon build a moat? Just because more people groupon, does it make competitors less valuable? Is it a barrier to have emails from livingsocial
and groupon arriving in your inbox every day? Groupon is almost the complement of fb -- fb had huge lockin, but no obvious monetization method. Groupon has obvious monetization, but no lockin that I can see.
I also question in the long run how many businesses have large enough customer LTVs that selling stuff below cost is worth it to hook customers. Hearing from eg hair salons that groupon people aren't customers but are bargain hunters isn't promising.
My prediction -- in 3 years, groupon will regret this if they haven't found a different sucker. Maybe comcast?
I'd be happy to be wrong -- it's always awesome when people succeed.
