Thank you for these blog posts. One thing that isn't immediately clear to me is how one should start a new open source library (before there is any traction) to be prepared for this structure of maintainership.
For example, I'm already a freelance developer with (my countries equivalent of) an LLC and I send invoices to my clients for my work. I'm also in the process of writing a few libraries in the mobile/desktop/web shared-code space that I want to release as open source. Should I just mention this on the projects Github and website properties? A simple "contact me for an invoice" link and process the invoices/payments manually? Is there a platform a la Github sponsors/Patreon that is compatible with this workflow?
