Personally, I think it's @DarthCoin
His guides would be super useful to noobs, but the grammar sucks and stops any noob from reading past the first paragraph. He does not take criticism well on this fact, either.
His replies to noobs are really mean too, and he calls people names like "pathetic shitcoiners" even when they are clearly only interested in bitcoin. Generally, his comments seem to have a mean/unpleasant edge to them and make the space a more negative place.
So, what do you think is the greatest hurdle for new bitcoiners entering the space?
Discuss.
