Everyone wants to know what you and your friends think, including Yahoo! (NASDAQ:YHOO). The website empire formerly known as the world's largest portal is a little more social today, thanks to its Alike, a ratings app for smart handsets.

Think of it as a more social version of OpenTable. Rate a restaurant in Alike, share with your friends, and the app recommends other places you might enjoy. Alike also allows users to rate bars and shops, according to CNET, which reported on the deal. Terms weren't disclosed.

Should investors cheer? Anything that gives Yahoo! a greater presence in mobile is likely a net win. But we may also be past the point where incremental moves matter, says Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova. In the video below, he argues that Yahoo! would have done better to make a bid for popular mobile directory service Yelp (NYSE:YELP).
