When I wanted to reach KayAnn one day, and wasn't sure she'd get an email in time, I was able to find her phone number because I had her name and address from the Christmas Card list from two years ago. I might have even been able to get it the old-fashioned way through an operator, but I found a few matches on Switchboard.com, and guessed right first try! I had to explain to KayAnn's Dad, who was a little (justifiably) suspicious just who I was, but that's okay. That's just how dads SHOULD be when a stranger calls asking for their kid!

We use that Google feature at work somtimes, when people give us a phone number, but no address, and we need to mail something to them. It's far easier than phone tag. It is also handy, just like reverse phone directories, when you've written down a phone number, and later can't remember whose it is!
