I wasn't raised doing a lot of around-the-house stuff, but in the past five years I've learned to do everything from recaulking a tub and rewiring lamps to fixing bicycles and repairing vintage rangefinder cameras.
I buy tools on craigslist and learn the steps online. Sometimes there's an unintended consequence to deal with (water spraying out of the sink, burned chicken, stripped set screws) that forums, skillshares, and hackerspaces are great at helping with.
None of this makes for a vocation, and I'm not advocating that people learn welding from eHow. But there's a lot to be learned from 'do it yourself' rather than 'do it for me'.
