My profile has a link to the flair page on it, so others can use them. However, it is a link to the flair page for me, because the
/current trick (which replaces "current" with the logged-in user's ID) doesn't work.
Can we have
https://%.stackexchange.com/users/current/x/flair redirect to the logged-in user's version of the page? This would be really nice; I could put it on my profile so people could have flairs, an obscure feature that I didn't understand for quite a while.
