Those regulars here who aren't also regulars at my son Ben's site should check out the post about his new favorite site.
Stuff White People Like currently has 81 entries, including the excellent newest one, Graduate School. The site skews a little younger and more liberal than I am, and seems to focus on the Bobo, coastal, upper-middle style of white person, but do not be deceived. For every entry which allowed me to snicker at the sort of white person I dislike, there was another which was painfully accurate.
That site led in turn to Stuff Educated Black People Like, which leads further to other "stuff" sites: stuff film critics like, stuff educated black people hate - Wordpress seems to have a salmon run on these at present.
