Apparently wardrivers (people who cruise neighborhoods with a laptop looking for open wireless networks) have been submitting their findings to WiGLE—a searchable database and interactive map of wireless access points.
Already checked—our home network isn’t in there. (As much as I’ve locked it down, it had better not be!) But they do list several in our neighborhood.
As always, the power of the Internet can be used for either good or evil.
