I think most of your advice is solid, but I take issue with one point:
> - If your font colour is more thant #333 on white, you're being cruel, especially to those who suffer astigmatism.
A designer should think hard before reducing contrast. You may be improving the experience for one group at the expense of others:
- A low contrast page is difficult to read on a cell phone in daylight.
- A low contrast page is difficult to read at night on a dimmed display.
I don't meant to discount folks for whom high contrast is a problem, but don't they have a simple recourse? Reduce the brightness or contrast of the display. Most monitors and laptops have controls that allow this.
