So this is a pretty fun map tool.
You plug in a bunch of addresses and it shows you where their geographic midpoint is. So if I plug in every place I’ve lived since 1995 (even those 2 months in Malden with the worst upstairs neighbors ever), I find out the midpoint is in East Watertown. If I just do every place since I moved into MBTA range in the summer of ’98 (at aforementioned house of horrors), the midpoint moves to a place just north of the Cambridge Public Library. I think I like that.
You can also enter two addresses and it shows you where you can meet up for lunch. Well, what neighborhood, anyway.
