It seems like yesterday that we all signed up for Facebook… but social networking actually has quite a history already on the web. This great infographic from OnlineSchools.org provides a look at the rich impact of social networking… from Bulletin Board Services to today's domination by Facebook and Twitter.
I do believe LinkedIn deserves much more of a prominent role in this Infographic than a simple byline next to some fledgeling (or dead) social networks. In my opinion, LinkedIn's value to the B2B industry is growing more and more. When it comes to business, it's my first choice.
