Computer-wise, I waste a lot of time reading various webcomics (
Paranatural is so good and so underappreciated and everyone needs to read it), TVTropes, and Facebook/Tumblr/Reddit (mostly r/leagueoflegends). Speaking of League of Legends, that eats up a lot of my time, as well as other games such as Warframe, Civ 5, the occasional DOTA 2 match, and whatever other games I happen to be playing at the moment (currently The Crew and Skullgirls).
Outside of the internet/college, I do a lot of screenwriting and editing for my school's student television network (the former with much more zeal than the latter; editing is REALLY tedious sometimes). On top of that, my friends and I have a Youtube channel (ForcedReset - it's in my sig) that I do a lot of work with. I also just hang out with my friends quite a bit - the usual activities being board games, Rock Band, and Smash Bros. Most of the console games I play are Nintendo and I play a fair bit of 3DS - recently I just finished replaying Platinum and I would be devouring Fire Emblem Fates if I weren't broke as shit.
I enjoy going to cons a lot - I went to both MLG Dallases a few years back, I've been to PAX East once and PAX South twice, and I'm planning on going to San Japan (an anime convention in San Antonio) this summer.
I'm also involved in a D&D campaign in case I wasn't already enough of a nerd.
Sometimes I play guitar (badly tho). I used to read a lot of novels but that's dwindled lately and I'm kinda sad about it tbh.
Also I have a girlfriend and that eats up a lot of time. tbh it's worth
