Sounds cool, but I think these innovations would transform my idea of what Facebook is into something like how I think of Craigslist or Groupon. Right now Facebook is where I go to see what my friends are up to. I think adding movie reviews, product recommendations, etc. might dilute its brand and its addictiveness factor -- in fact, I think they already have. Some commercial-type messages have already started diluting my news feed a little bit. Google, despite having relevant ads in its sidebar, is still just a search engine.
