How the streets of San Francisco got their names: a fun little history lesson, nicely formatted as a giant clickable map (with search if you just want to look up a specific street).
Google Maps now does satellite images which is pretty cool (zoom all the way in), and what everyone predicted they would do with the Keyhole software company they bought. The part that freaks me out is finding my own house with my own car in the driveway, taken last fall (by the looks of construction in the neighborhood). I guess it's time for all of us to have our Streisand moment and wonder when satellite imagery has gotten too good. [via]
