Sorry about the search box being inaccessible. When designing it, I took into consideration that 99% of my visitors arrive with >1024 pixel vertical resolution. I'm curious though: as a lifelong Mac user, is your 575px-tall browser window limited by your screen resolution?
Nope. It's limited by the fact that otherwise it covers up the rest of my workspace. (Though my sister until recently had a computer with an 800x600 resolution, which would also not be able to show the search box with all the toolbars on.)
And I didn't mean it as an attack or even a gripe: I mean that it's a lot of work to make a product where everything works perfectly for everyone, and even you fall short. You go further in many areas than most people, but that's just a question of where to draw the line on accessibility, not whether to draw it. IMO, if we want better accessibility, we need to make it easier for people to get further before they feel like they have to draw a line.
