Tons of people are getting things done everyday around the world. Zed happens to be part of the subset who are promoting themselves agressively on the web. Not that I think that self-promotion is bad. But it's important to recognize the distinction between promotion and productivity.
I have been thoroughly impressed with how productive Zed can be.
whether or not he is good at promoting himself - and he seems to negatively affect enough people that the point is arguable - he is good at getting things done, people who fail to acknowledge that reveal more about themselves than they do about Zed.
