I myself have never worried too much about it either as it really doesn't change peoples minds about who you are as a person...but in circumstances such as tutorials, the dislike bar is so helpful[DOUBLEPOST=1375389119,1375388902][/DOUBLEPOST]
So true, it just annoys me so much to even see people making videos about haters and stuff like that. in every from of art you will get people not liking your stuff simply down to your appearance and disregarding talent...so YouTube really is the same in that aspect!
