I signed up for a free account on Plazes today, even though I’m supposed to be working. Essentially, it’s a geotagging service that uses the network you’re currently on to place you in the world. This might seem intrusive, but can be easily switched off. It allows you to annotate a network by providing the specific location, pictures (even from Flickr!), and notes. It’s also a social network, so you can have buddies. Pretty cool. Give it a try.
