There was an article on HN a few weeks ago about a guy making a game out of LinkedIn. In that he made a fake account, filled it with buzzword skills, degrees, and colleges. Started adding every notable person he could. Then it became a domino affect. Once he had some influential people as connections, other people started adding him, thinking he was then a big shot. Then once he got a ton of influential connections, recruiters from major companies started reaching out to him with job offers and interview requests.

Ultimately LinkedIn does have a good business use, but it can also be gamed pretty hard.

EDIT: Found the link. It didn't originate on HN, but I saw it from a post about it on HN.
