> photos I like taken in New York in 2010 - great way to find something again without filtering through activity log or remembering (all the) details
> friends in Austin, Texas - because _people move_ and I travel
> friends who like ultimate frisbee - I meet a lot of people and play a lot of frisbee, it would be stellar to have an auto-populated list of friends (not just the regulars) who would be down to play
> friends who like Book of Mormon - who should I be asking for a recommendation?
> people who going to event X and event Y - now we can carpool
> people in group X and group Y and group Z - similarly
> Stephanie who went to Mike's event and is friends with James - use case from below (that I encounter about once a month) of trying to find someone with a sparsity of details.
