That would be Facebook, it is by far the biggest. Even when compared to Twitter, FB is much much bigger.
No that is not correct, Facebook has 400,000,000+ individual users. That number grows exponentially every day, while myspace's membership has been on the decline for some time now.
That is true, but they are running into some problems these days because of privacy/security issues. They need to figure that out if they want to keep growing and if they want to keep current members, a lot of people are unhappy about that right now, most of them young adults around college age.
Yes, Facebook is the biggest social networking site, has been given alexa rank 2, nest to Google. This shows their how far better is their traffic.
Very true, Facebook is the leading Social Network Site. I will not be surprised to see going in front of Google soon.
I heard that it passed Google the other week, but that was just word of mouth, and therefore not reliable.
Facebook is definitely the biggest social networking site with Myspace coming in second. I think alot of the Myspace users are in the process of mitigating to Facebook.
They say that size doesn't matter. Its how you use it. This is true with Social Networks. Even though Facebook is the largest if you are not utilizing every ability that it has, then you might as well not be using it all.
Mark Zuckerberg himself - "As of today, Facebook now serves 300 million people across the world." and that was in September of 2009. There is no point in arguing this, something has to be disputable to argue it. In terms of what is biggest, Facebook is by FAR the biggest, and that is fact, close the case, game over. Now we could argue about what Gvann said, and whether or not it is more useful than other social networking sites. Which is certainly debatable.
