Privacy tip: be wary of Google's "personal history" feature
[Imagine the type of personal information that a subpoena to Google
could unearth in a criminal prosecution: every search query you've ever
made on that computer with that browser. If you "log in" to other Google
services, your queries can be tracked across computers. Can this
information be obtained by opposing counsel in a divorce case? I don't
know, but I can imagine some instances where it could be seen as
relevant. I'd invite someone with more knowledge of family law to reply.

Google retains logs of *every* query. I refer you to the following
It's far from clear if 'pause' actually stops logging, or just
marks any queries made as 'not to be returned in History'.
Google also places tracking cookies on your machine, and
presumably uses them to identify the queries of a given
If you setup some google service which requires you to identify
yourself, that cookie can be used to link all of your queries
to your identity.
At that point, the privacy implications become immense. While
some will always respond 'If you have done nothing wrong, why
would you want to hide?', in the real world, there are many,
many values for 'something wrong'. Actions and interests
that you, today, may feel are ethical and legal, may by some
one else or at some future time be used adversely against you.
Its a matter of privacy.
