During the past year we have been doing a fair amount of work to create a profile experience that re-purposes common profile data and segments a users contribution by audience type.  Even though the UX is fairly simple it has been tough works getting the internal business units to agree on a common interface that will scale and grow over time.

The main focus has been to create a UX the support who you are and what you have done within each audience segment.   We segmented the user’s activities by audience so that when another user is viewing your activities they are relevant to other like people.
