What public data you access is in itself private data. Even if you don't care about your personal privacy, I think we should all care about the chilling effects of people not being afforded privacy to look at public information. That people can browse Wikipedia, and their ISP / government is prevented from knowing whether the article being read is about knitting or a political issue is a good thing.
