He's a very interesting guy who I thoroughly enjoyed interacting with at the anti spam conferences he set up. As a speaker at the conference we got to visit his home where he graciously hosted many anti spam geeks with his own resources. Our conversations were always interesting and funny - he has that smart almost British wit about him.

He's been incredibly lucky to be a smart person who managed to make his seed money, and then use it very wisely to turn it into what I guess is now many times what he invested.

It is a shame he has become so busy lately that he can't interact as easily with the "common man" any more. I emailed him not long ago and got no reply. I guess that happens when you have hundreds or thousands of emails in your inbox every day (a problem he has listed often as one he'd like to see solved by a startup).
