They might not be great in the worse case scenario (a site asking for proximity alerts for many locations), but they're pretty good in better scenarios (e.g. a single location). Also, a user agent could better give guidance to the user when a site requests alert for too many locations, or refuse giving alerts when too many are requested, or when they are to close to one another, etc. Dom
