Facebook Reports Another Privacy Glitch Social networking giant Facebook reported another privacy glitch this week that caused a mix up in their messaging system. User's private messages were sent to the wrong in-boxes, further irritating fear over the site’s security. Yahoo and Twitter Team Up Yahoo announced this week plans to team up with Twitter to provide real time search result into its search engine.

Apple Cleans Up Its App Store Apple caused quite a bit of commotion this week with their new efforts to clean up their iPhone app store. After numerous customer complaints, Apple removed over 5,000 “overly sexual” apps their store last week. As Apple executive Phil Schiller explained in an interview with NYTimes this week, “It came to the point where we were getting customer complaints from women who found the content getting too degrading and objectionable, as well as parents who were upset with what their kids were able to see.” While such arguments are valid, it seems that Apple has been a bit selective in terms of what 'racy' apps are allowed to stay and which have to go. Apps built by Time Warner, for example, like Playboy Enterprises and the Sports Illustrated Swimsuit addition, haven't been effected by Apple's housecleaning. For more information and a detailed list of which apps survived the cut, check out Rich Jaroslovsky's article in Business Week.
