@nprofile1q... yes and when the person migrates accounts the note follows them (I should probably edit to add that)
For example I have a note about you and here's what the field says post-migration:
"This user moved from [Handle] [@] weesecake.social, here were your previous notes about them:
My friend!"
So it doesn't work if they idk make a gamedev alt or something but don't migrate the account but it's useful.
I used to store birthdays in here then realized calendars are a much better way to do it
