One of our favorite rogue digital archivists, Jason Scott, has just posted a video of his talk at DefCon 19 about The Archive Team exploits. This is perhaps the most eloquent (and freely peppered with profanity) explanations of the problems inherent with preserving our digital cultural heritage. He also describes in a fair amount of detail what he and The Archive Team have been doing to help remedy the problem.
I am going to take a moment here and say that THIS is what I was talking about a few weeks ago. Jason Scott and The Archive Team exemplify the type of community activity that we need to be happening in order to save our shi.. stuff.
