Facebook might be the biggest social networking site on the planet, but it is still playing second fiddle on home soil to MySpace. However, now that the Comscore numbers are out, we had to see what Facebook and Myspace did last year.

In 2008, Facebook had 54.5 million monthly unique visitors compared to nearly 76 million for MySpace.

Even though the gap seems to be narrowing down, given the current growth rate (in 2008 Facebook was at 3.8% and MySpace only 0.8%) it’s still unlikely that Facebook will emerge no.1 in US by January 2009 or even the end of the year. However, 2010 could be a different story altogether.

Start up site Ning made the largest strides forward in 2008 with a growth rate of 388% while Classmates came in third behind MySpace and Facebook with some real good numbers and a growth rate of 66%.

It seems that the battle for social networking supremacy on American soil is getting hotter by the year, isn’t it?
