An email account, showing the domain only.

Buidling homestaking stuff HomestakerOS.com

Email different than the one you used for signup? Would a pure domain verification work better?

Yeah, the idea would be to verify current employer or some other novelty. You could prove in a separate field that you work for e.g. Coinbase or that you study/do research at MIT or whatever without spending space about it in your bio.

yes - if you do this, you could give users the option to enable the domain favicon for their company to display next to their name on casts
