This is a good reminder. I received a phone call one day from a recruiter on the west coast (I'm in Toronto) right around dinner one evening and was caught off guard. I had to ask how they'd found it and they explained.

I'd forgotten where I'd made it public, and did so intentionally, but had forgotten.

There are some solutions for email addresses. I use something like this on my website: http://wbwip.com/wbw/emailencoder.html

And for what its worth I put my website in my profile where my contact info is available
