Editing Reddit (section)

==Current Status==
As of late, Reddit (as well as Twitter) has become the subject of many memes and jokes regarding the fact that their users have no lives, are stupid, or else any combination of the two. Some attribute this to the great Tumblr exodus, where some of the homeless NSFW artists migrated to Reddit.

While it would be overall foolish to say that Tumblr users alone have effected Reddit's reputation, the widespread willingness to mock Reddit also comes from the stereotypical arrogance of their userbase. Which to be fair, 4chan could also be accused of the same thing, but 4chan at least doesn't have people accusing each other of attempting to harvest upvotes every time they post.

TL;DR: 4chan largely despises Reddit's userbase for being preachy, arrogant, and generally loud-mouthed idiotic assholes. The feeling is mutual.
