Social media now accounts for 18% of time spent online, according to a new infographic.

Since 2006, the amount of time that the average person spent on social-networking sites has more than doubled, from 2.7 hours to 6.9 hours per month. More people are using social media, as well. While only 24% of Americans had a single social-media profile in 2008, 56% of Americans do now.

Between the different social media sites, Facebook is, unsurprisingly, king. The average Facebook user spends almost seven hours each month on the site — that’s well ahead of Tumblr and Pinterest, which tie for second place for most time spent. The average visitor to Twitter, LinkedIn and Google+ spends less than half an hour on the site per month.

Social media isn’t all community, collaboration, and cohesion. It has a dark side too. It’s a perfect tool for tracking people and conducting surveillance as well as spreading propaganda, and it’s wide open to all comers, no matter what their purposes.

I am about to commit an act of meta-journalism. I’m sorry. I hate meta-journalism. I unfollowed GigaOm’s Mathew Ingram a fine writer on Twitter some time ago because I could not muster any more interest in articles about articles and blog posts about blogging. I believe that journalists like people in most professions vastly overestimate their own importance, significance, and interestingness.But I suppose if I’m going to go meta, an end-of-the-year post seems an appropriate venue; and for once I have something both meta and relevant to talk about.
