I agree, some of the channels mentioned are just doing videos for the sake of videos and revenue. They are too long with very little content. Sometimes they rope you in with a suggestive title and then you find out it's like 1 minute of content out of a 25+ minute video, and the rest is filler or generic. That rubs me the wrong way. I can always tell when $$$ is a motivation, it's way too obvious.
I did a video review of my sawmill last year, no motivation other then being a satisfied customer, and it started getting a lot of views, almost up to 300K at this point. I've since done a few others on tree work and milling, and some projects. Basically, whenever the mood strikes me and I feel like I have useful info to share or teach, I'll do a video. Some are short, some are long. It's not a job or an income, and I don't try to make the videos fancy. If it gets views, great, if it doesn't, no big deal. Every video has seemed to help at least a few people, which is all I want to see.
I haven't done a video in several months due to lack of stuff to talk about, but I'll probably do a follow up review for my sawmill and film some lumber production. When it's convenient and I feel like I have relevant info, I do a video. I couldn't see turning this into a job where I need to crank out content every couple days to survive. That's when things seem to go downhill for the bigger channels.
There are quite a few small Youtube channels related to sawmills and tractors that I have come across because they view my videos and leave comments. These are all small time guys sharing helpful information, and in many cases they are real characters that are fun to watch. I feel like these smaller channels are the real gems on Youtube. They are authentic and enjoyable.
