Facebook, Twitter, NeoGAF. :-(
It really feels like a lot of that stuff is getting "closer" so to speak. I mean, I'd hope I wouldn't really socialize with dumbfucks, but even among people I trust and respect I've encountered lines of thought that were so illogical and tinfoil-hatted that I couldn't help but facepalm internally.
The internet makes it way to easy to build your own detached reality. It's my most disliked aspect of the internet by far.
