No, I am saying that viewership of that stuff should grow organically, and no hugely successful tesla "youtuber" actually comes to TMC and posts ANYTHING about ANY of their videos.
I know of one specific very successful youtuber that is an active participant here, and never (ever) mentions their site, their videos etc. They dont promote themselves at all.
I am saying that, at least making a post and then trying to use some sort of "media content" style "tease" with either the title, or NOT answering the question you posed with anything other than "I made a video about" is a quick way to get people to hit the "ignore" button since its so easy on this specific forum to ignore someone digitally. You run the very real risk that, because of the fact that you have several posts styled like the above, people are going to "hit the ignore button" and then wont see ANY of your posts, so you may miss out on actual conversation you want to have here, if there is any of that.
As far as the bolded part above, sure, people benefit from demonstrating costs... however costs can be demonstrated with a spreadsheet MUCH better than a video. Some people get value out of demonstrating features, for sure. Good videos tend to get linked back here by participants, NOT the content creators themselves. If you enjoy making the videos, make them and post them to youtube. Either they grow organically or they dont. Posting them here and saying "I made a video about", trying to drive people to your posts, is going to backfire.
