All I know is that it doesn't look like it's worth that much. And supposedly the prices at the similar
GetSatisfaction start at $1200/month (you can see it on the pricing page if you make your browser window narrow, haha!)
This just continues a theme that's popped into my mind a lot this year. The house prices in my city... $600/year for pay TV just to get coverage of your favourite sport... $700 phones... hundreds of $$$ for DLC in a single PC game, sometimes even before the game is released. Probably somewhere some wise person said "I admire you when you say money isn't everything, so give yours to me."
