As much as I want to see reddit torn apart by every feminist with access to a mainstream media column for /r/beatingwomen over the course of a few weeks, I will tentatively come to their defence in some form by saying that's it's not just reddit.

Reddit's structure and system might make it an echo chamber, but it's an echo chamber for a certain type of internaut which exists already. During the Boston bombing aftermath I tuned into @youranonnews to get the updates. I think the mentality is egocentric (even though I fed off it for up-to-the-second information), and it may well be attracted to reddit's warm strokes and upvote-for-mutual-validation practices, but it's limited to the reddit.com domain in the slightest. Anon had a police scanner (an online version I think) and were posting everything they heard on the scanner like every second via twitter. Equally, they didn't get stuck into photo detective work in earnest until someone posted 'convincing evidence' assembled by some kid on 4chan. So it's not just reddit.

Eventually the snowflakes and general losers of the internet will make their way to the reddit honeytrap, so maybe it will ultimately become the largest congregation and clearest example of this perspective, but it's not reddit.com per se.
