Hey guys! This is going through some tweaks today and should be giving you a shiny badge if you hit 100% by the end of the day.
For those stuck at 90%.... The current 'profile bio' requirement requires you to have filled out your 'About Me' section in the profile. We'll update this as well though to consider favourite music, films, hobbies etc (any of the open text field options). That might be what's holding you up.
