@Jon – wonderful comment, thank you – really like the notion that this stuff needs remixing in order to have a life at all (ie, remix is everything not just an added extra). I think you have a very good point there.
I also do agree 100% with looking to other successful media outlets and asking how we can employ what they do in our institutions. This is one of the reasons I’m forever requesting “museum” conferences and meetups should be not just populated by museum people congratulating each other on the wonderful projects they’ve done, but should encourage speakers from elsewhere, whether it’s Flickr, Google, “commercial” (eek!) or otherwise. To separate out museum concerns from the concerns of all these other rich outlets of content is to do our users a tremendous disservice.
