What part is continuing to improve in quality? (this is a serious question)
I see production values and the sponsored tools go up in quality but not the actual content.
Just because ad revenue is up, it does not directly translate into better or higher quality content.
There are MANY channels out there that have clearly spent more time, effort and money on the filming of the video than in the content.
I, for one, would much rather watch a one or two camera simple production of a skilled presenter/craftsman than a Hollywood production of some "content creator" using tools he has no clue how to use.
