Who will buy this wonderful social network? Its valuation’s so high, I swear it could fly… Yes, Twitter is reportedly up for sale again, but this time there appears to be serious interest in taking the social network off the market. CNBC reports that Twitter “has received expressions of interest from several technology or media companies and may receive a formal bid shortly” with Google and business-tech firm Salesforce among the potential suitors. The speculation has already sent Twitter’s share price up by more than 20%, with Salesforce’s ‘chief digital evangelist’ Vala Afshar stoking the fever with a tweet explaining “Why @twitter? 1. Personal learning network. 2. The best realtime, context rich news. 3. Democratize intelligence. 4. Great place to promote others.” Recode reported that Twitter is looking for $30bn in any sale, and tipped Apple, Facebook, Disney, News Corporation, Comcast and Verizon as others who might be interested.
