Wikipedia is contributing to the slow death of what could have been, and almost was, a web of independent pages maintained by individuals and groups. I have had a recurring experience of skimming a Wikipedia article, only to get the feeling that the text is familiar - then tracking it down to the book or article that it was lifted from, without attribution. If a "vibrant free web" means routine copyright theft committed by a homogenizing, centralized collective established as some kind of anonymous authority, I can do without it.
