Security -or- do I really need a VPN

[nightsong]

I guess it only matters if you care when people know where you are?  I know some users have been as broad as "somewhere in the midwest", others are more comfortable with only their state (or province.)  I think most don't want to get down to which city they're in, unless it's a big city that would be hard to track them down. Sooo... knowing that the sites you mention are NOT exact locations, and I'm not sure of any publicly available site that does (not to say there aren't any...), can you tell me why they recommend having a VPN?
