Facebook asking you to rate Places

I just noticed this, not sure if it’s new or part of their A/B testing. They’ve got a box on the right hand side asking which of two places I have previously checked into was better.

It looks like Facebook are trying to gather information about places so they can provide recommendations, much like foursquare’s Explore tab.

Have any of you noticed this on Facebook? Answer in the comments or on Twitter @arunstephens.
