Obviously, there's very likely to be some holes in the data. But once you login somewhere that's associated with Google, you're known. From then on, you're databaseable. Before that, using the world's largest database, that's already been databasing you, it's a matter of correlating the trend of what you're doing with someone who's been databased for doing the same thing, to establish a probability that it's the same person. While that's fraught with errors, it's the evidential methodology in solving a crime (fit the likely pieces together until you find something very corroborating that links to something provable, then you follow those links back in reverse). But I think most people will identify themselves, somewhere, by logging into at least one service, and that service will be one of Google's, or something they've got a finger in. I think this happening will be far more likely than people think might happen. And right now, a search engine probably knows your IP, since they could have indexed these emails (with headers), and you're probably not doing anything to hide it. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
