“Like” – yeah, maybe. But it seems to me the accounts are definitely – or at least arguably – not identical to someone’s home. Now what?

And every time I catch myself thinking I have no sympathy for people who cry “privacy!” after posting personal information on these social vanity sites, I also think how I would react if information I post when paying bills, or ordering a book, or even posting like this, were subject to surreptitious search. This is an important issue for our age.
