Great source of music videos, but in common with the rest of the internet it is clogged to fuck with valueless self-indulgent crap posted by moronic teens. Youtube comments are great fun to troll due to lack of moderation and proliferation of easily-offended fanboys.
Typical Youtube comment thread:
