@readwriteas not sure I understand the separation of writeas and readas. And if I don’t get it, non technical people definitely won’t.
I recommend just keeping one domain for writing posts and also reading them. Something like medium. Medium defaults to reading content unless you log in and decide to create a new article.
So why not have the writeas website default to reading and discovery? After you log in, it gives an option to create a new article for yourself?
