There is a new Linked In Follow emblem to add and a short programme script to embed in behind it to activate things. When this is clicked from your company Website you are then invited to login to Linked In to view the company's Linked In profile, news and so on, which then counts you as a follower.
It is another useful development in the expanding business social media communications. I think it still remains unclear how important a role these features will play in the future success of a business but for now many companies are taking no chances. Time will tell.
