I'm not sure why but if I look up specific tasks I do find what seem like capable handy man / plumbers or similar folks with good quality advice.

Medical stuff.... oh gawd almost no chance of good advice there. But maybe that's because the range of "hey we don't know" or "it's complicated" that you're going to get from honest folks when it comes to the medical world, and most folks gravitate towards solid answers that hucksters love to give.

Hucksters might find it hard to monetize "how to cut down a small tree", while "cold remedies" are prime grounds for them.
