Here is a site that seems to have taken off in Scandinavia, so to speak: Flightlog.org lets people upload and share their GPS enabled paragliding flights. Why share? I asked myself that too, until I realized that the original impetus of the site was (and is) to act as a clearing house for paragliding races.
What’s new, and the reason I mention it here, is that all the flights in its database can now be viewed in Google Earth. For example here is a flight near Stockholm that ended up ditching in the sea.
