Iain Thomson, The Register:
"The Federal Trade Commission (FTC) may be expanding its antitrust investigations to include the increasing integration of Google+ into Mountain View‘s search engine business.
Additional probes into the links between Google and its fledgling social network are being ordered to assess to what - if any - level Mountain View is favoring its own services in the search engine market, two sources told Bloomberg. The FTC declined to comment on the matter."
I closed my G+ account last night. Not too happy about my posts being so obvious in Google's search results. They want us to share everything public, but I want it privatized. If I do an all private account, I get threatened of closure. What's up with that? It's their service yes, so I'll just leave and continue using Facebook.
It's funny this comes on the heals of google fighting sopa/pipa.
Whenever you sign up to these things though you risk this. Like Racer said, even if they offered you options to delete completely. Your info is probably sitting around on a server somewhere.
