gives me the idea, rank news items according to geographic distance, and "blast radius"

closer to you gives higher rank in the feed, tighter blast radius lower rank.

example, events in your present location rank higher, events 100miles away rank lower. police stopping someone for a seatbelt and issuing a ticket, likely ranks lower, vs evacuation order for city ranks higher.

a cheap way of assessing relevance score.
