LinkedIn, the business-focused social network, has again edged slightly outside of its own high-walled box with the introduction of a new ‘Follow‘ feature for businesses.

The new button can be placed on websites and, if clicked (and if the user is logged in) will let the user start ‘following’ the business and its updates on LinkedIn.

In other social media news, Facebook has started rolling out its mandatory change to bring the ‘timeline‘ feature to its fan pages. This will change the look of pages dramatically, allowing for better use of video and imagery and allow pages to post ‘milestones’ at any point in history – early adopters Ford using it to post an update about the launch of their Model T in 1908! More excellent examples were recently posted on Mashable here.
