Today Yelp launched their implementation of Facebook Connect to enable users to share reviews with their friends on Facebook. After you post your review on Yelp, you are prompted to post it to your feed. That’s about the extent of the service but it’s definitely another large site to integrate with Connect. Aardvark, Etsy, oDesk, The Washington Post, and many more have also implemented Connect in recent weeks.
Facebook has invested heavily in building out Connect, attempting to get as many sites to implement it as possible.
