Back in the day, Dopplr used to give you an annual report of your data based on your travel footprint. They may still do this, but I stopped manually entering my trips into Dopplr years ago.
However, since July 2009 I’ve been “checking in” at locations across the country — more than 2600 places, actually — on Foursquare. And when you animate those checkins, categorize them and set them to a trippy instrumental soundtrack, you’ve got yourself an ego-feeding over-share frenzy of awesomeness.
As geolocation-based socnets evolve into maximizing ambient location (why should I have to check in if my phone knows where I am/was anyway?), look for even more of these big-data-meets-personal-data experiences.
