Meebo, chat service confirmed that Google has bought it outright, presumably for improving features of G+. As a web-based instant messaging client, Meebo has been around for a while. It also features the Meebo Bar, which overlays sites that users visit with social sharing and instant messaging capabilities. They can get customized recommendations and targeted ads by creating their own profiles. It has been rumored that acquisition price may be $100 million which, if true, would mean about a dollar per active user of the Meebo services.
