I was under the impression you don’t have a lot of space in the bio, so I’ve always kept mine very brief. But yeah, that’s an option.
I’m thinking more for publications with the footer idea, as in general one flaw with Medium is how old articles can look dated in terms of appearance and defunct CTA. I’d love a way to keep a publication looking more uniform over the years with changes you make to design and your CTA/social links.
