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. Unlike Google and Bing, Yahoo plans to limit the number of ‘tweets’ they index to two, but plans on coupling them with relevant YouTube links.

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.  Yelp Gets Suit over Disputed Review A class-action lawsuit was filed against Yelp this week that alleges unfair business practices and claims that the online local review site has been running an “extortion scheme.” According to the New York Times the suit claims hat Yelp’s employees “call businesses demanding monthly payments, in the guise of ‘advertising contracts,’ in exchange for removing or modifying negative reviews appearing on the Web site.”  This is not the first time Yelp has run into trouble  for their lack of transparency and questionable poliicies regarding reviews and businesses.
