Home Ec, what's that?
Basically, "stuff to help me keep my household clean and organized and running well."
What about stuff like http://www.handybook.com/?
That's falls in the category, certainly (well, "cooking for the home", which differs somewhat from "cooking for a restaurant", which wouldn't really be Home Ec), but it stretches much further.
"What about stuff like http://www.handybook.com/? "
Falls in the broader space, and might be part of a broader solution, but probably most people aren't going to outsource most tasks so there's still a lot that doesn't cover.
