If you’re a grouchy mechanic and do boring videos of exactly how to do brakes on every car, that’s incredibly useful, but not subscribeable (unless your grouchiness becomes a meme).
I feel bad for the one guy that did 1 perfect video on how to fix&overhaul my garage door opener. But he won’t see a cent even as YouTube puts ads on it anyway and takes 100%.
Meanwhile on blogs etc with Adsense, you could monetize immediately. That’s how i started out and figured out what worked. Went from $2/month, to 20 to 200 to 2000 for a while. Lots of random articles. Didn’t care to become a “platform” (new users that visit and never come back are the best ad-clickers).
