Social Networks: Facebook Takes Over Top Spot, Twitter Climbs

With Facebook officially turning five years old recently, combined with the site surging past MySpace in Monthly Unique Visitors, it seems like a good time to take a little deeper look at the social networking giants.

It’s hard to believe that last year around this time we discussing the effects of bad PR for Facebook and if the site had "˜jumped the shark,’ but those arguments now seem to more appropriately apply to other properties.

A year ago, we ranked the top 25 social networking sites by monthly visits, and I was curious to see how the positions would change if we re-ranked those same sites with the most recent figures.

Some key metrics in the health of a social network revolve around the activity of the user base — visits per unique visitor and time on site. While Facebook has excelled in both areas, MySpace has remained flat or fallen off, with new hot property Twitter climbing the ranks.

MySpace is still the clear number two player in the big categories, but its trends in some key areas aren’t quite so dominatingl and, at least in those areas, they could be looking up at more than Facebook soon.
