One more amateur history of technology site and then we move on to other things.  DigiCamHistory.com provides an enormous—if poorly organized and badly designed—wealth of annotated photos and links relating to the development of digital camera technology.  Like the evolt.org Browser Archive, DigiCamHistory solicits user contributions, and although it is hard to say how much of its content is user-generated, the organizers' stated interest in collaborative collecting once again suggests that amateurs may be our best bet for extending the practice of online collecting.
