The site is a mess. Comments appear under videos in no logical order. It is not uncommon to come across thee ramblings of an irrelevant blogger that have, for some unfathomable reason, been posted to YouTube. The raised character limit means that instead of people sending each-other private messages, even longer blocks of intellectually sterile bilge are posted on comments pages. Every time you try to post something, you are asked where you want it sent to. F**k, I don't know. Maybe the YouTube comments section? Aye, that'll work.
Oh yes, and you keep being pestered to show your real name on YouTube. Google Plus? Yeah? No, I'd rather die.
