Hi Lea!

This is a complex issue... I'd like to toss some psychological issues on the table... because they often get swept under the rug.

Let's be honest here (and a large part of this can also be attributed to YouTube having a long history and blockchain social being much newer), most people...

Get on YouTube to create video content to hopefully make money

Simple enough. Now, when it comes to dTube, most people..

Get on dTube to make money, through creating video content

Couple of things here: These two may look the same, but they are not... and that's where your point about people getting here and stopping is well taken. If your primary intent is to "create videos" you're going to take a different set of expectations to the table than if your primary intent is to "make money."

Incidentally, this same issue plagues all of the Steem ecosystem, including the blogging front ends.

But we have a bigger issue. Whereas the 7-day window might discourage some, the bigger factor here is that there's plenty of incentive to try to drive 300,000 people to view your video through Facebook, twitter and Instagram when you're a YouTube publisher... but "external views" have ZERO VALUE here. So "why bother?" Which also speaks to your point of perceived maximum rewards in each place.

Finally, there's the whole "blockchain" issue. Those of us who are here know about the coolness of blockchains and crypto... but your average bear on the street doesn't care one whit... they just want to post their videos somewhere. Or their blog. So a pitch that includes (as many do) a lot of singing the praises of blockchain technology is gonna fall on mostly deaf ears... except very technically inclined ears, and those aren't necessarily the most suitable content creators.

In a sense, I would have to submit that successful dTube marketing, attraction and retention needs to focus on careful niche marketing. Try to attract specifically the people who are sitting in "great quality but struggling to get traction" on YouTube area, and show them a better way to create.

In the meantime, though, we do really need to consider finding reasons for people to create "evergreen" content... because with that 7-day window, there are none. And I was RAISED on evergreen content! But after two years here? I barely CARE whether what I write today will still be timely information in a couple of years...

I know someone out there is working on an initiative to help reward content creators for "old" posts through some kind of commenting scheme... keeping my eye on that one.
