No. I feel Reddit culture has had a negative influence on the Internet's ability to hold reasoned discussion.

I got my first email address in September 1994. That doesn't quite make me part of Eternal September but that's only 'cuz I took a year off. Prior to having an email address I'd seen CompuServe and had done MUDs on green'n'white scroll paper daisywheel printers using acoustic coupling modems. I say this to establish that I've been on the Internet since before it was the Internet. I was a full-time denizen of several rec. and alt. newsgroups before DejaNews, my first IRC experiences were over a 2400 baud modem, and I remember the BBS.

My first experiences with Reddit were shocking. Even back in 2007 Reddit was far and away the most vitriolic, abusive place I'd ever bothered to venture.

4chan is worse, no doubt. But 4chan was relatively isolated. See: Cracked, July 2007. 4chan also did not gamify caustic aggression the way Reddit did. I mean, I got 700 points for a caustic beatdown of a spammer back when /r/pics had 60,000 subscribers and it's only gotten worse.

/b/ was effectively the origin point for most of the Internet's memes... but /b/ didn't gamify. Reddit did. So the people who wanted to be rewarded ventured over to Reddit where they got points. So Reddit became the origin point. It also allows ranking which makes the content browsable by casual users, whereas 4chan is linear. By the time /b/ figured out they could get points for f7u12 cartoons it was over.

Reddit is one of the meanest places on the Internet, and it rewards meanness. The more Reddit spreads, the less personable the Internet becomes.
