The way I see old videos is like they are a part of my channel. Everything I have ever posted has helped me get to where I am today, for better or for worse, now if a video were to eventually cause mass offense in some way or I were to make a massive mistake or something that was simply just not good, only then I would take it down, out of demand, respect, and thought. At least, that's how I look at it. I mean, I don't want to be known as a minecraft YouTuber, I no longer post videos of the game, or play it really, but I won't take down my videos I did post, they are still a part of what made me, me.
