A lot of hate for Vlogs here, maybe not hate, I think a vlog can be pretty good - if the person is doing something interesting or are one of those really good story tellers, you know the people who you meet sometimes who can just hold your attention.
I generally dislike prank channels tho, a camera is not a free licence to get up in peoples lives and do stuuf to them. And some of the things we are begining to see are getting to be a bit extreme - wont be long till someone is killed and laws are passed I reckon.
I know that this is going to be an unpopular opinion but I think, at the moment at least I am least fond of game channels, everywhere I look I seem to run into one. I do like them when they play really odd games though. I am so bad at hating.
