I post to TA and Yelp both. I tend to use Yelp in the US to give me a range of ideas, then look at other sites to get a better range of detail.

Sometimes I use a part of another app to get ideas then go to Yelp etc. to refine. For example, if I want to find nearby places with a good beer selection, I look at the "nearby bars" part of Untappd. Then I find that place in Yelp or Foursquare to get broader reviews.
