On Ask Fedora and Fedora Discussion, we have a profile field for pronouns. It is an open text string where people can provide what they want.
I have noticed that many people have, somewhat confusingly, given their first name or username here. Others have given what I suppose they think are clever responses, which are generally (as my kids say) more cringe than cute.
I am thinking that it may be best to have a limited-option dropdown, with these choices:
* [blank] * she / her / hers * he/ him / his * they / them / theirs * other (see profile)
... with the last option for folks who sincerely use neopronouns, or if someone _really_ wants to use their profile space to go on about their personal beliefs on the topic for some reason.
Your advice appreciated.
