> there is also a technical barrier that works both ways. most don't have the capability to have a regularly updated website with content that otherwise would have been put in the file drawer. and the other side of that coin is what audience will actually find / read it online.

Add to this: the ability to get things indexed properly in google (scholar), easy way to update metadata, server availability, dois, apis, etc. I contract for neliti.com and we provide stuff like this now for orgs/journals and conferences all over the world outside of the US for en, id, tr, ru, uk, es, pt, and ms locale content (pdfs,xmls,docx, datatests, etc.) but mostly a lot of indoensian orgs/journals and conferences, with ~40 using their own custom (sub) domain we route for.

I hope that eventually the landscape moves to a place where these services can be provided for individuals too (lots of upstream stuff like dois requires having an organization which i think is stupid in this day in age where any piece of digital content can easily get an identifier, related org or not).
