Has this guy played with Interfave Builder lately?
This guy writes a lot of well executed but fundamentally vacuous articles; I wrote about a previous one here: http://jseliger.com/2010/09/30/computers-and-network-effects... last year. At this point, PG's essay: http://www.paulgraham.com/trolls.html applies to him. But you wouldn't notice as much from any individual article or submission; it's only through the collection that his tactics become apparent.
