Why? Because it's obvious to me that the publics, in the Internet age, have more or less forfeited any notion of privacy. Nearly every Web enhancement is a strike against privacy (track your data, have your entire banking history on a server, et.al.). That's fine; I'm certainly not complaining.
But, vis-a-vis a PR person taking notes, I found this peculiar given how much people put of themselves online, via blogs, podcasts, whatnots. But that's it - individuals want to be the ones cataloging themselves. It's totally fine to have a dossier on oneself, as long as "I" am the author.
