I'm happy to admit there are many of them I simply don't get. But then there are some I do which put me in Smug Mode. (Like "Oranges are ok, grapefruit FORBIDDEN!". Umm, it is from lileks.com, right?)
I'll have to start writing down all the ones I go 'WTF?' about and tally them up. Erm, this could turn into a kind of LRPD purity test :)
