If this was turned into a permanent link, I think it might be worthwhile to start over with a poll that leaves the option of putting your LW name attached to your location.
Even better, if you could hover over/click on a plot point, and have their name pop up.
For example, instead of just knowing that there are 2 people located within driving distance, you could know that Person A and Person B were within driving distance.
Even better would be to have the option to attach a zipcode to your account, so that people can check where you live, and so that you can manage your information easily if you change locations (or want to obfuscate your location by repeatedly altering it, since I know some people will want to do that). Additionally this would allow implementation of location-specific actions (eg, you get an email if a nearby meetup is announced), which could be very convenient.
Earlier this month, Metus did a post asking for LW-ers locations. I thought it would even more useful to have this information in visual format, so I created a Google map. You can access it on the website below. Unfortunately, I am terrible at this post-writing interface, so I can't get the image of the map to load onto here. You'll have to click the link to view it.

(If you haven't filled out the poll yet, please do it! If more people submit their location info, I'll add them to the map.)
These are only for US locations that had a 5-digit zip-code, or a city name. I may or may not map the other countries. If someone else wants to volunteer, send me a message, and I'll add you as a collaborator to the map, so you can edit.
