That was an interesting downfall to witness that taught me a lot about how Reddit really operates. I'm the beginning, it was actually a quality alternative to the generic front page repost subs like /damnthatsinteresting.
Then the instant it hit 1 million subscribers, the whole mod team changed, people like Turtle suddenly appeared in the name of "helping out with a sub that grew too fast for existing mods," and within a few days it was just another trash repost sun.
