Hello! I have an idea for Keyoxide.
Maybe it should be possible to add a bio to your profile with markdown. It could be done with a GPG notation that could look something like bio@keyoxide.org=BIO, where you replace BIO with your bio in markdown, with newlines being indicated with \n.

e.g., if I add a notation with the content bio@keyoxide.org=#Hello\n*World*, it should look something like:

Hello

World

Maybe you could also add pronouns, looking something like pronouns@keyoxide.org=he/they...
