Good point, however time is used daily by almost everyone, whereas lat and long are used (directly) by far fewer people. The main problem this would have is people figuring out what the hell it means! Most people have some grasp on latitude / longitude and although they may not know how to read/use it, they could probably find out. A random code without obvious meaning is going to be a whole lot less appetizing... At least until it gets popular - I mean look at what twitter did for url shorteners... maybe that's the way to integrate this. Or get google maps to implement it, and use it in their location code (it is shorter than lat/long coords and they already use these in their queries, and they are concerned about bits transmitted...)
