No amount of features will get me to use this; there's too big of an initial hurdle to making the system aware of what I like, and I don't have a pressing need for more recommendations of things like films and books. This needs to get tied into something like Facebook or Yelp, where I can just give you my password and it suddenly knows everything I like already. That's why Mint.com worked for budgeting - unlike everything that came before it, I just gave up my account numbers and suddenly it knew how I spent my money. No more manual entering of stuff.
