I'm 55 years old. My eyes are not what they used to be and neither are my glasses. I also own a copy of "Usage and Abusage" but I'll pass on that. Click on story link. My laptop renders a page - OK its black text on a white background (thank you but I doubt its a deliberate boon) ...
... why on earth is the offering a "page" ie emulating a printed page? In portrait!
I'll accept that most people are not fixated about grammar, punctuation or basic decency: that's fine.
However a "page" in portrait that looks awful on a landscape screen is unpleasant. You can easily request my viewing parameters and adjust accordingly. It's even worse when you are dispensing advice about www page layouts.
