Brush strokes? Oh, puh-leeze. Isn't the difference between "drawn" and "lettered" characters explained around page two of any typography textbook or calligraphy manual?
Got a vague idea w### is also responsible for the canard that catchwords originated as an aid to "illiterate bookbinders". I finally gave up on arguing with this one because, hey, who cares about facts when you've got a good story?
Can't say I am wildly impressed by the hieroglyphics idea though. How did serifs springboard over the millennium or two between classical Egyptian hieroglyphics and Roman inscriptional letterforms, skipping over all intervening graphic traditions?
Besides, serifs delimit all ends of a stroke, not only the bottom.
There was a spell in the '50's or '60's, give or take, when Germany had some kind of overreaction to fraktur and tried to put everything in sans-serif. Mercifully it didn't take hold.
When your printer is twelve dpi, sans-serif is definitely a safer option :)
