I read that article yesterday. I thought it was a very good piece on the differences between NetBSD and Linux. Seems the main root of the differences between the two OS paths is in the philisophy of each. Linux development seems to be a frothing stew, or a rapid unorganized explosion of development. Then there is the Net/Open/FreeBSD side of things where everything is focussed on tight organized development.
Then there is the Debian/NetBSD project [debian-bsd.sourceforge.net], which sort of disrupts everyones view of the natural *nix order.
