i always liked the freebsd.org design. it's clean, functional, good to look at.
can't really say the same about openbsd.org. clean? yes. functional? yes. good to look at? no. and freebsd is actually w3c correct... this is my biggest pain (as a web dev myself) as openbsd is very robust in everything else. but, no problem, can't be best in everything ;-) -f -- mexico's greatest export: their population.
