ShaderToy is a mature and very large community, thus, you can find all types of shaders there. But I can ensure you that there are a lot of users at their platform doing their best to help beginners. FabriceNeyret, for example, comments on lots of shaders, giving optimization tips and making constructive suggestions. Yes, there are some hard to figure shaders there, but there are also very experienced users helping the community. And thanks for the suggestion, I really appreciate it. I'll do my best to make more "documented" shaders to share the little I know with the community.
