Suggested social profiles should be sorted according to contact's address whenever possible. Say I create a contact and specify an address, with all the fields (city, state, country). It doesn't make sense to be suggested contacts from Paris if I told Nimble my contact is in New York. Many Linked In, Twitter and Google+ profiles have some geographic region information. It's not necessary to make complex geolocation queries and sort by distance. Probably just string matching (city, state, and country) should be enough to improve this. Common names are most affected by this behavior.
