A company with $200M in revenue that generates littel to no cash or income has almost $5B market cap. It gets and upgrade and automatically flies to that number. Other stocks get upgrades and it takes months or years to get to that share price.
Manipulation at it's finest. Meanwhile, the insiders just keep selling and selling.
It's competing against GOOG, YHOO and any other site that offers the same type of service. There are 1000s of local sites. This will end badly. The concept can easily be challenged. The cost to enter isn't great. Literally any internet company can compete in this space.
