Current implementation appears to translate geoloc to a city name and distance is based on central point, not actual location. My city is around 270sq/mi, some members listed as <1mi could be 15 or more miles away. Potentially this could be resolved using the current location name as a display but for calculation and distance estimates using a truncated lat/long and haversine equation, and then display based on distance groupings. if done server side, it would greatly increase accuracy without disclosing specific locations. as an aside, the potential to check in to specific pibkic venues/locations would be a bonus.
