Geolocation evolution

I think geolocation is going to be the next big evolution on the Internet:

With iPhones and other new mobile devices building in GPS, and now larger devices like laptops getting easier to geolocate, will sites like MySpace and Facebook start giving users the ability to attach location information to their posts? drop.io already has a drop location feature which allows drops to be assigned a location, so that they are only visible by devices which are close to that location. Features like that seem to tie in nicely with functionality like Geode.

Of course, this opens up a whole bunch of new privacy concerns. But, netizens these days seem comfortable publicly posting just about everything, so adding location into the mix may not really upset many people.
