Facebook Usage by Age Group

So I found out today that Facebook has some sort of demographics information based on what people are talking about in their posts. It's got only a few different topics, which really comes down to 3 categories: Politics, Sports, and Music. This is the basketball graph, but it looks like all the other graphs for the most part. These graphs really only show me facebook usage/communication throughout the week based on age. This is for all facebook users.

I find it interesting that the most active facebook communicators are the 18-24 range, and they talk least on Saturday (the low point on yellow, must be a weekend party thing). the 13-17 age group is least active on facebook on fridays (low point blue), possibly due to end-of-the-week assignments. Usage picks up throughout the weekend. For the most part people use facebook least on the weekends and more throughout the week.

I found this info on http://www.new.facebook.com/lexicon/new/?demographics&topic=basketball

I just think this graph is cool to look at Facebook usage, you might find it extremely boring.
