Youtube is a black hole as a viewer! I go on there to look for inspiration or advice on something and look up and discover that it's 3 hours later. As much as I like instruction, I get a lot out of watching people make things just to see their technique and how they use things differently than other people.
Fair warning though, as far as comments go, Youtube is known to be harsh. I know most of the Soapers I've watch seemed to have a lot of supporters but I also know that they get nasty comments that can stick like thorns.
I don't think this should hold you back from doing it, but I think an eyes wide open policy is always best so that these things don't take you as a nasty surprise. Let's face it, if we never did anything for fear of criticism or just plain nasty people, nothing would ever get done!
If you're unfamiliar with editing software, you might want to look into that first. Your videos will be much easier to shoot if you can just edit out the parts you don't like.
