LinkedIn has announced the launch of the it’s new ‘share’ button. Publishers, bloggers and businesses can include a button on their site that lets readers and visitors ’Share on LinkedIn’ by adding a few lines of code to their websites.

In the past, publishers like The Huffington Post have integrated LinkedIn share on their website. Starting today, sites like Bloomberg, Forbes, and the Mercury News’ SiliconValley.com are doing the same. In addition, they are also integrating even more advanced functionality like the ability to sign-in to your site with LinkedIn credentials.

The challenge is for LinkedIn to compete with Twitter and Facebook for users content sharing activity. However, as the ‘business’ social network, this new tool is viable as an effective way to share relevant professional content – news, thought pieces, white papers, or presentations on slideshare – with their business network on LinkedIn.

I think it will take off.
