(Moving comments from the non-political thread here.)
If it's not being already done, soon all user names will be indexed with real names and all of the info online about you into one huge data file . . . viewing habits, subject matter, health, clothes preference, foods, morals, politics, etc. . . . all available on a subscription basis.
I can see how forum posts supply lots of psychological info. Wouldn't take much to tweak that sort of data for unwanted purposes, even if it seems benign. . . targeted political voting, etc. Heck, why vote at all, when a data base can match your political beliefs with a suitable candidate.
I would guess many will disagree with me on this (and I'm rambling a bit), but I can't see how it won't happen. The Internet is going to turn out to not only be the beginning of a communication revolution, but also a privacy intrusion revolution. Who's going to stop huge corporations from buying info or buying the companies that collect the info, or just colluding like the NSA does? Internet privacy law doesn't really exist, or at least been truly litigated. The government will want the data just as much as M Soft or Exxon does. It's going to cause huge problems because people will be scared to speak up . . . . right after the first major objectors speak up and suddenly their "private" lives are made public, possibly including details that aren't real or true. (Can you imagine trying to fight stuff released about you that isn't true?) In any case, my doom and gloom predictions may be way off the mark, but then again they might not. This is a good example of hoping for the best but expecting the worse, but how do you stop the worse when you don't even know what's happening in that dark place and by nameless people. It's like a J. Edgar Hoover wet dream.
