I'm private, therefore I'm not?

On one hand, the search engine subpoena matter put many people in a stir last week about rights to privacy.

On the other, the thoroughly blogged New York Times tome, A Generation Serves Notice: It's A Moving Target (reg. reqd., in case you're one of the three people online who don't know that), lays out the "millennial generation's" (that's teens-to-early-twenties, in case you're ... oh, never mind) obsession with being connected.

I summarize it as: I'm online, therefore I am.

If you believe your connectedness defines you socially, you should be prepared to trade your privacy like baseball cards. No online activity affords any guarantee of privacy, because no single entity capable of and interested in guaranteeing privacy actually controls any Internet request end-to-end. Get used to it!

I wonder if privacy concerns are as strong among millennials as older generations, members of which I keep hearing tend to go online to complete life tasks more than to socialize. Any data out there on that?
