"News Sites Getting to Know You"

" The Online Journalism Review has a story about more and more news sites requiring registration. Has assorted facts and figures, including how much sites' traffic dropped when registration was required.
Even though a fair percentage of people just make up the data they are asked to provide, I'd guess that as a statistical measure it's probably pretty accurate - many people would tell the truth without caring that they're being tracked."
