Computer science PhD student Randy Olson likes to analyze reddit in his spare time. We saw his network of subreddits already, but his look earlier this year at the evolution of reddit is more interesting. The yearly breakdowns and explanations are the best part. I'm relatively new to reddit (and totally feel like an old man when I visit), so it's fun to see what the site used to be. More news and fewer Scumbag Steves, with a humble beginning in nsfw?
