"It probably puts you in the location of your ISP's exit point"
If so I think it would display the telephone exchange, or the one upstream, location. Instead it shows a small town in a mountain location far away from both. MaxMind GeoIP service maps it in the center of the largest and closest city, but it maps several IPs there, so it's of little use for precise targeting. I guess many attempt to get a better fix for IPs, but dynamic allocations can lead to big errors.
