Semi visible text
Not to mention the absurd contrast theft which plagues "modern" websites. The Register is in the minority with its crisp black-and-white text. Many sites are now only readable with constant eye strain. Or they were until a few months ago. Those who brought us semi-visible text are now in full reverse-ferret, but my accountants still server up limp whiteish on whiter text, and Google search is still pretty gutless.
