Google's latest endlessly-beta project, Search Mash, looks decent. All Ajax-y. I'm only considering it because the jerk who writes InquisitorX has discontinued Camino support. And after I paid for my copy, too. Inquisitor makes the search box in the upper right of your Safari sing and dance in various niftytastic ways.
Random aside: At 3pm sharp, Mr Pedia starts hassling me about when he's going to get to watch the new Torchwood. I believe I have watched one episode of Dr Who from start to finish in my life: the one with ASH. I have no idea how many he's watched. Wait... he says zero. I'm sure we're missing huge swathes of backstory. The Wikipedia article has the usual obsessive nerd details, but I dunno if I actually want to read them. The series should stand or fall on its own, perhaps.
