User Profile Field Categories

[testbot]

there's not really a whole lot about it so i'm not sure if i'm doing it wrong or what.

i created a category named Social Networking
Location on Profile Page: Main Colum, Last Tab

then created a User Profile Field> Single Text Field> with the following
Name Facebook
Category: Social Networking
Private Field: No
Field Searchable on Members List: Yes
Show on Members List: No
Display Page: Options Other

finally, i go to my profile and add a value to the new field, look at my profile and no new tab named Social Networking.

am i missing the purpose of this option?
