- Facebook is alive and well, even among the < 20 crowd I know. I love using it.
- Several of my friends use Tumblr, but I don't get it. It looks like a mess to me; I have trouble spotting the content I'm supposed to look at.
- A lot of my friends were on snapchat when it first became popular, and the content they sent me was sometimes hilarious, but mostly boring. Most people I know have lost interest.
- I've never been able to get into Twitter.
- I LOVE reddit. I'm one of those weird people that finds the default front page hilarious (granted, it does get old after a while), but the more time I spend on it, the more I appreciate how it allows me to connect to people I never could have met in real life. For example, I was curious what police officers thought about a recent shooting in my hometown, so I posted to a law enforcement subreddit and got perspectives from all over the world, including from officers in New Zealand where they don't regularly carry firearms. Another time I was discussing SSL on the redditdev sub, and a reddit engineer jumped in and explained why reddit doesn't force https (infrastructure capacity reasons).
