Don't know how many of you do this already, but I noticed someone doing it to me today. I have a nice little YouTube following, but I get sooooo many comments on certain videos that I don't even answer the comments anymore. I noticed a guy today with a similar YouTube page on the same niche and similar tutorials going down my comments answering people's questions. Of course his name is right there and he's establishing himself as a helpful authority on the topic. Go ahead and let him, he's helping people. But I wonder how good a tactic this is to get other people's followers to come follow your YouTube account. Just a thought anyhow if anyone wants to use this tactic.
