Just some guy, dude.
I don't check out people that ask for sub for sub, I DO however, check out channels that would like to get feedback or are wanting to create similar content to me and see my opinion. It's all in who you pick, and how you ask. Some I've subbed to
Careful. A whole lot of people will ask for "feedback" and "opinion" just as a way to get you to watch their videos.
