(This nostalgia moment is brought to you by "Where in the world is Carmen Sandiego?", the geography action adventure from my youth that I actually remembered when I wrote the title.)
It was hard for me to decide whether to leave another data trail, but it's a way too tempting opportunity to meet interesting people, so I registered at Plazes anyway.
Plazes lets people register where they are and displays their location on a Google map. You can choose your current location manually on the website or even let the "Plazr" application (available for all common operating systems) do it automatically for you by deriving your location from your internet gateway address.
So, if you want to know where I am at a given moment, go to Plazes and ask for "Geewiz". And if you're in the neighborhood and would like to drop by for a coffee, let me know!
