Slightly OT, but my pet peeve is the growing number of sites that assume a minimum browser width that is wider than I like to keep my browser windows, as if everybody kept their browser window maximized at all times. I still read old bare-HTML sites often enough that I don't like to do that; I prefer to keep them about 800 pixels wide. Too many sites won't fit; some of them even manage to turn off the horizontal scrollbar, a neat trick.

I think the largest minimum width any page should assume is 640. I could live with 800, but 1024 is too wide.
