I had an email early this morning, followed by a phone call later on, from a recruiter looking to fill a position in London.
He got my phone number from the contact page on my blog. He got to my blog by doing a Google search for Jonathan Hodgson, who I've met at a couple of DeveloperDay events. He did this search because he knew that Jonathan works for the company he's recruiting for, and decided to use Jonathan's network of contacts as a source of potential candidates. I haven't decided whether I like this approach or not yet, but either way, I'm impressed with his resourcefulness.
