The world’s chief web filter is of course Twitter; we’re there.  So are most of the people below.

Arts and Letters Daily, perhaps the most intellectually ambitious of all links pages (on Twitter)

Barking Up the Wrong Tree, questions and answers (on Twitter)

BoingBoing, a filter blog with a lot of tech, some art, and occasionally a ukulele or two (on Twitter)

Crooked Brains, galleries featuring bold design and whimsical products (on Twitter)

Dark Roasted Blend, lots of little text linking to interesting things (on Twitter)

Fark, which began as a picture of a squirrel’s genitals, and now is a big traffic driver (on Twitter)

haha.nu, mostly visuals

Jason Kottke, one of the oldest continuously updated sites on the web (on Twitter)

Neatorama, funny stuff (on Twitter)

3quarksdaily, rather scholarly in its focus (on Twitter)
