What about YUI/YQL/YSlow/Hadoop/Boss/Pipes/Flickr/Yahoo News
Yahoo still exists? How quaint.
"But beyond needing to replace Yahoo! Finance, my daily life wouldn't change all that much if Yahoo! suddenly disappeared. Would yours?"
No. I never use Yahoo!
I don't either, but it's all my dad uses. I suspect we're not their demographic.
Yahoo is the second most visited site on the internet, according to google. [1] So I think there might be more people upset than you think. Plus all the people on flickr would be pretty pissed.
