I also see these sites and apps taking on more and more ideas of one another.  Latest is Yelp adding a “Check in” function to their iPhone app, basically competing with Foursquare.  Then I think about the fact that Yelp canceled their deal with Google.  What are they planning?  Or could another party have a better offer and be more suited?  Could Facebook be interested?

Could there be a social consolidation wave coming?  Where Facebook will go on a buying spree and thereby add more social functionality and consolidate the information stream?  Or will they buy one of the social consolidation apps and provide a concentrated place for all your streams?

I do like the new elements, the clearer navigation in the left column, the icons in the main nav bar.  The only thing I don’t agree with is the location of the search field.  IMHO it should be in the right upper corner and have the main nav items reside where the search field resides now.  That way all the nav is located in the same general area, making it more obvious and more efficient (less eye/mouse movements to navigate).
