How should I be googling for an email address in a way that minimizes false positives (while avoiding false negatives)?
That is, just searching the email address isn't enough, since you end up with a lot of false positives.
For example, searching Adam@lifehacker.com doesn't really give conclusive results, since Google doesn't treat the @ as a string-preserving character. (I'm using the email address of the editor of Lifehacker as an example, since its publicly available, ie, on the Lifehacker sidebar).
Searching "Adam@lifehacker.com" is better, but its still subject to false positives.
Lately, I've been trying "(adam@lifehacker.com)", and it seems to be a huge improvement over the other two.

{first} {last}" brings up dozens of other people that are Not me. I'm fairly sure that if someone wants to be contact-able they will provide an option to be found. ;-) – scunliffe Jul 19 '10 at 13:18
