There are other networks as we all know, but the difference them and Facebook as this comScore chart underscores is huge under scored by the ocean of activity, news stories and blog posts that poured out last week as it launched its new Facebook Timeline at f8.
When you use Twitter it feels like everyone is on it, but then you look at this and the story is very different. As much as 90% of all time spent on social networks is spent on Facebook with the rest filling in what’s left.
