The issue of sharing examples is good - and Google Earth is an ideal vehicle for outcrop examples (and maps etc). Of course, an issue here is about collecting the array of interpretations that could exist for a particular suite of outcrops (and individual ones).... and it's interesting to consider how you might locate content - not on the geography but on the geological interpretation (e.g. "find all fold nappes"). It's less straightforward given neo-synonyms (many "fold nappes" might be classified by some of the community as "thrust sheets", rightly or wrongly (which is the interpretational aspect), not to mention different languages)....
These are issues we've tried to address using structural (and other) interpretation of seismic data... on the Virtual Seismic Atlas. Since I last plugged this (about a year ago) on Geotectonics, the VSA has grown, in content and function.
We can now provide user IDs to individuals that provides access to a structured authoring environment ("MyVSA")- and you can add (?competing?) interpretations of seismic images that we house (a kind of wiki meets the Bally Atlas). In addition - if you've got the appropriate permission from the data owners - you can upload your own complete case studies (e.g. "clean" seismic plus interpretations, or even clean seismic on its own to ask for interpretational assistance). The VSA allows you to add your own weblinks direct to publication portals (e.g. Geoscience World) and/or to your own homepage... and you can include mpegs etc for movies....
Although this started out as UK based, through this year we're rolling out the project to partners internationally - so if individuals would like to get involved, please contact me [DIRECT - DON'T HIT REPLY!!]. Otherwise - everyone is free to enjoy the images (you can browse anonymously, and download, subject to honouring the IP of authors etc). Even if you're not interested in seismic itself, you can see how we've handled the issues of interpretational metadata. Unfortunately, we don't have any fold nappes in ...... (or at least, interpreted ones)....

Hi Bill
although perhaps not entirely what you are looking for, Tectask (The Task
Group on Tectonics and Structural Geology of the IUGS) recently started an
initiative called Outcropedia (see links from the front page at
http://www.tectask.org ) that aims at hosting googleearth/kml based
structural sites of interest (either single outcrops or whole field trips).
We are still debating how best to provide this service, but Tectask hosting
of kml files and images is and will remain part of the system.
cheers
