This is a great point, and one of the many reasons I have a blog. I'm always left rather bemused when I do a google search for someone and come up with nothing.

This is a great point, and one of the many reasons I have a blog. I'm always left rather bemused when I do a google search for someone and come up with nothing. If the person had put up a blog (or really, I suppose, a public web presence of any kind), then we might have mutually benefitted from an interaction. It's the same reason I share all of my (non-proprietary) code on github, even the "useless" stuff. You just never know what might serve as the focal point of a valuable connection.
