Your Google Reputation
I Google everyone. If you cold call me on the phone, I'm Googling you while we talk. I Google all meeting participants before every meeting or conference call. I Google everyone who I interview or who interviews me.
Valleywag (yes, I read Valleywag) has a rather tongue-in-cheek (as is their style) article on managing your Google reputation. However, there are some good lessons there.
