I am finding that YouTube clips work ok in the context of blogs. But it is very slow. Direct questions are not easy to put and answers can take ages, not always arriving from where you expect. The clips have to be short and people choose how to combine them with others.
The blog posts I start with offer some sort of structure. I am going to try less fixed opinion to start with. The aim is to combine various links or sources. Look for conversations over time. I have a lot of background photos of seats in public places. Avatars could be pasted in as time allows. And subtitles added based on some sort of sources.
