My Sleep Habits: Fun With Facebook, Part 3.5

(Previous post here)

I'm not making this a full post yet, because I don't feel like writing much but I still want to share this cool result. Basically, I got a working HTML parser for Ruby and am beginning to create a framework for analyzing the Facebook data stored in HTML. My first interesting result is this graph for frequency of wall posts (including status updates) by hour, in military time:

Interesting conclusions to draw here:

1. Facebook seems to indicate that I'm asleep before 2:00 the vast majority of the time.
2. The drop for the 15 hour (3:00-4:00) PM is probably related to going home at the end of the high school day, which ended at 3:50.
3. The other drop at 19 (7:00-8:00) PM is probably because that's when most people eat dinner.

Coding this took almost no time, so I'm super pleased with the cool results I got out of just this simple test. I'll be able to refine this particular dataset later once I can take comments into account too.
