Sometime during the last few years people started to provide how-tos and sometimes documentation for various topics by uploading a video with audio commentary to YouTube.

Please stop doing that. The average human can read about 250 words per minute - way more than we are capable of speaking.
There are videos for trivial tasks on YouTube that would take only a few lines to describe and maybe a Screenshot or photo. Still, people are producing low quality videos with bad audio which do not get to the point within the first third of the time (see Wadsworth constant).

I appreciate the effort, I just hate the method.
