Very true... One of the guys originally involved in managing one of the world's largest USENET servers in days of yore, was talking about the decisions he and others made as to what was worthy of being moved to a long-term archive. He now deeply regrets preserving primarily technical discussion while discarding reals of messages about abortion, women's rights, Communism, and _many_ other historically significant issues from the very time they were still living issues. Just try searching Google Groups for any of these subject with a time constraint that puts you back to the dawn of USENET. However, a search for say the eccentricities of some mod to System V on some peculiar piece of hardware will probably have survived.
