Sharing funny articles with your high school buddies who you haven't talked to in ten years is one thing, but sharing business-centric items with colleagues is a whole different ballgame. LinkedIn, the social networking site dedicated to business professionals, has launched a share button that publishers can attach to their articles to link content to the site.

LinkedIn has made several moves to make their site more content friendly with content sharing and resharing amongst others and this is yet another step to make content easier to access and share on the site. No one's saying that the In button will be as plentiful around the Internet as the "Like" button, but it's a step in the right direction if they can get the big sites to implement it.
