The news - which is expected to be formally announced on Tuesday - comes one week after Facebook marked its sixth birthday by revealing it has more than doubled its number of users in the last year to 400 million.
Google and Microsoft’s search engine, Bing, have recently looked to incorporate social-media services to make their offerings more relevant for users also active on SNS. In October, both Google and Bing announced they would adopt a Twitter function to reflect audiences’ growing interest and trust in social commentary. Microsoft was first to launch its Bing Twitter Search function and further connected with Facebook to offer search results on users’ updated statuses.
Further blurring the lines between search, portals and SNS, Friendster and Yahoo Southeast Asia last month also entered into a multi-year strategic partnership that lets mutual users more efficiently share information.
