Jep, can confirm that. Lately i watched a bunch of vids on youtube by jawoodle. Used to find him entertaining, but he's exactly how you described. Had to hit the mute button after a while. Then left video cause without him commenting his actions it seems totally unreasonable what he's doing there.Then switched to neebs gaming. Constant chattering there too (well it's not that unexpected there, because there is four of them).
These guys can be quite entertaining, but also r e a l l y annoying, according to how much beer you had before, and how vulgar their trash talk gets.
Well thats the point overall i guess: you have to be in the right mood yourself when watching a guy playing and commenting.
