true story - i have never in my life advertised my channel on anything other than my own channel.self advertising is pretty scummy, and looked down upon by pretty much everybody that sees it.
You've seen ppl on youtube commenting on other ppl'smore successful channels to get advertising for their shitty ones
make good content, and people will check out your stuff. Use twitter, put yourself out there - just don't put yourself in OTHER people's venues trying to get a slice of the people going there.
deplorable.
