Greetings Piotr,
This is a great point you bring up. (about engagement and one way street). Seems there is no real incentive for content creators to engage on their videos, as it takes quite a bit of time, and unless they are making a living from youtube, it seems pointless indeed. If they are making a living from youtube, they will likely have so many comments that it will not even be possible for them to get through them all, and then they lose too much time. It's not an efficient system.
It does make me think a bit about Steem engagement as well. I think it would be great if there were some large accounts solely dedicated to rewarding engagement. For example, as a top ten stake holder in the weedcash tribe, I make it a point to reward engagement, especially the comments that take time. It doesn't even matter if I agree with the comments, I reward them because it makes it worth their time to continue engaging!
Wow. Your experience is even worse than mine. crazy ...
I kind of "fed the beast". I knew instantly I was dealing with a moron, and shouldn't have even bothered playing into it, but hey.. Sometimes it happens. The lesson here is don't bother engaging on youtube..
Thanks for your support and kind words Piotr,
PS. I just responded to your email :)
