@jwz Well, now that you've brought up BLINK...

When I first saw that tag in the HTML spec, I was convinced it was put in as a sop to convince advertisers that they could migrate over from NAPLPS (used by the Prodigy online service), which defined a blink attribute, and which also got overused.

Also: The browser that shipped with BeOS -- NetPositive -- had an easter egg in it where, every 100th blink, the blinking text would be replaced with "Buy Now."
