Many Youtube commenters and Chat members are engaged in a frankly silly argument in the Youtube comments. The Chat has forgotten that Youtube is not there to praise The Chat. Youtube has forgotten that the Chat is not there to amuse Youtube. Both are there to let SuperGreatFriend know what they think about his Let's Plays, and to maybe not be jerks to everyone.
If people on Youtube do not like The Chat, it is easy to scale down the Youtube window to cover up The Chat and not read them. If you think someone is trying to get attention, don't give them your attention.
If people in The Chat do not like hearing criticism, it is easy to not read the Youtube comments. If someone is trying to make you mad, don't let them make you mad.
