Just stumbled across a new concept: folksomologies which is obviously a portmanteau word that I found in Technology and geography: some work in progress by Barry Brown and Louise Barkhuus (a paper from an workshop at ECSCW).

a number of the same designs or concepts are being replicated time and time again, with little in the way of innovation. For example, the ‘tagging’ of locations with information has become a frequent feature of geographical sys- tems, yet there is still little in-depth enquiry as to whether this tagging supports activities of genuine interest to users. (...) In our current work we are exploring much more the choices that individuals have in their location and mobility. We are also interested so called ‘folksomologies’, ad hoc structures that can be built and span across different locations.
