Here is my honest opinion:
Nobody will create a video because there is a thread about making videos.
Nobody will make a map because there is a thread about making maps.
Nobody will make a campaign because there is a thread about making campaigns.
And so on...
Intrinsic motivation is needed.
Just make a video instead of talking in great length and detail about making videos without any result.
Just make a map instead of talking in great length and detail about making maps without any result.
Just make a campaign instead of talking in great length and detail about making campaigns without any result.
And so on...
If you make a video and start a youtube channel, people will watch it.
If you create a map, people will use it.
If you design a campaign, people will play it.
And so on...
If someone needs help, they will ask anyway. But they most likely will not read long threads. At least that is my experience of 25 years of internet.
For example, I have an other hobby: building Lego Star Wars Creations for a RPG. The RPG is almost dead, like this forum. But it is fun to build the stuff, so i would do it anyway. Intrinsic motivation! Here you can see them:
