4chan has got a lot of stuff done. Consider the HWNDU saga: https://www.youtube.com/watch?v=vw9zyxm860Q https://www.youtube.com/watch?v=vw9zyxm860Q Obviously this is trolling, but it damn impressive they found it. They've done quite a lot of other stuff including finding ISIS targets and getting them killed, using nothing bit a sheet of paper and an innocuous message to make the media look silly, they've even caught animal abusers. Plenty of people stick their nose up to them but they are probably one of the more effective online communities. It just depends whether you happen to like what they are effective at.
