If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
I long ago simply set up window manager keybindings for Google and other sites, so I just hit mod-g 'keyword site:lesswrong.com'. If you don't have a hotkey set up for Google... I recommend you set one up. If you do nearly as many searches as I do, you'll find it pays for itself in weeks.
This used to work better before, I think. It seems google doesn't index most comments these days. I suppose that's what causes this whole problem then, huh?
