LinkedIn, the biggest professional social network in the world, announced it reached an agreement to buy lynda.com, an online learning company for $1.5 billion that will be paid about 52% in cash and about 48% in stock. For LinkedIn it’s by far the largest acquisition made in its 12-year history.

With a bare statement, the FriendFeed team announced that the social network will be shut down. From this week it doesn’t accept new registrations but users can keep on using FriendFeed for another month. On April 9, the social network will be shut down so its services will be no longer available. The cause is the decline of users, due to the fact that the development of the services had ceased after the acquisition by Facebook.

Yesterday, when it was early morning in the USA, Facebook started having problems. Suddenly it became impossible to update your status or write anything in groups and pages and even use the “Like” function. Soon, on other social networks, mainly Twitter, messages were posted showing panic but also irony and #facebookdown was very trendy among the hashtags. After a few hours the fault was fixed and the situation slowly went back to normal.
