2) Ratings

What does this translate to?     #review@business
Heavy competition for yelp. If you mention any business or product using hash tags it might get to that particular product/business in future.

Twitter and Yelp on their own had issues with their business model. Put them together and it might become a bigger beast.

I wonder if facebook is trying to pull this off.

Facebook placing itself to hit Google and Apple at the sametime.

Here are the two interesting news from Facebook -
1) Facebook is trying out a technology to trace your cursor.
2) Facebook is in talks with Blackberry to see if it can become a device player.

Now connect the dots.

Currently, Facebook is trying to trace cursor for Ad improvements only within Facebook - But in future, after becoming a device player, (if successful) Facebook might trace cursor whenever you use the device.

But then this is just a smaller shine in a bigger mine - Transition of Facebook into a product company will entirely change the game with closer integration of facebook into a device- fmail, fcalendar, fmovies, fmusic, fstore, fapps etc.
