The mileage that Zed Shaw has received on a simple well-designed Python SMTP library is absolutely astounding and totally disproportionate to the complexity, novelty, and general market need for the library. His only other notable contribution is a simple, feature-constrained single-purpose micro web server that uses a scaling-limited thread-per-request architecture.
[Edit: This comment doesn't really make much sense now, since the parent updated his comment to note that Zed ALSO wrote mongrel. I'd delete this comment except for reply attached to it.]
[Edit] Why is the reply nonsense? The point is fairly clear -- there are far more established, widely used, complex and important projects that do not have such vitriolic personalities attached. Zed Shaw's known for his blog posts, not because of any proportionally notable contribution to the open source community.
(The original unmodified comment referred to this reply as "nonsense").
...but, OTOH, it worked out well for ESR...
