I recently began testing a clients Web Portfolio for rankings, so when I typed in their first name in the top three search engines, the first result was always a Facebook user with with the same name as my client. When I clicked on this user to see who exactly she was, her profile picture was a professionally taken model shot and she had over 500 friends! I was tempted to tell my client to send a friendly "poke" to that user to obtain friend status with this top ranking user.
So whether you hate it or not, Facebook is huge and probably here to stay for a while. If you haven’t already started taking advantage of it, signing up as soon as you finish reading this is a start. Here is a pretty astonishing chart showing just how large the gap between other social mediums rank against Facebook. On top of that, with the aquisistion of Friend Feeder (Twitter’s competition) and a launch of Facebook Lite , who knows how much Facebook will dominate in the future.
