Whoa!!! Have you discovered Google's fantastic personalized Internet Search History?
Of course, I trust this rather personal information is only available to me, and not to any others. This includes some law-enforcement officers who might want to look at it, e.g., "Canada's Largest ISP, Bell Sympatico, informed its customers that it intends to "monitor or investigate ... your use of your service provider's networks ... and to disclose any information necessary to satisfy any governmental request."
Note "request" -- that means *without* any court order...
The article says most other ISPs will soon follow. For all I know, the large U.S. providers are already on board.
This will reveal a significant portion of my personal life to any "law-enforcement officer" person who might have a grudge against me, or perhaps might decide I was a "respected person" who should be taken down. All this person has to do is make a request, and start data mining. I'm sorry to say that I've watched this kind of vendetta happen, on multiple occasions. We know that some obscure law-enforcement "officers" seem to relish this kind of twisted anti-social activity. Sadly our system favors them, with secret no-defense-council grand-jury proceedings, and a whole panoply of fearsome expensive tools.
OK, all that aside, the Google Search-History tool is awesome!
