I browse reddit unironically. I've been doing it for the past month or so. The quality goes up and down depending on the subbreddit. Some of them are extremely 4chan-ish, in a "culturally homogeneous to the point of the userbase being virtually indistinguishable". If they appended everything with -fag, it would be literally 4chan running on another platform. Also the people at reddit like to jerk each other a bit more than 4chan, and by a bit I mean a whole fucking lot. Stroking it among each other seems to be like their favorite sport.

But really, it's surprising that the folks at 4chan and at reddit don't recognize each other a whole lot more. From a bird's eye view, they are pretty much the same young (and white) audience.
