What problem is REALLY bugging you? 
nudge: Right question, wrong place.Ask teachers, dentists, gardeners, councillors, vets (both the animal-doctor and the ex-military kind), fish owners, fish eaters, mechanics, little old ladies who don't know whether to trust their mechanic, landlords, concierges...You're more likely to get responses you would never even have considered.Look at it this way. It is often said that the best teams / startups are formed of people with different backgrounds, different thinking styles, different worldviews. So you're not going to add much to yourself by asking people (broadly speaking) similar to yourself. Find people totally unlike you. Think of a business you've never even encountered. Does it suck to own a fast food franchise and be totally at the mercy of the brand? Who knows? Maybe it does. Maybe you can help a little. Is it tough to be a guitar teacher nowadays when I can sort-of learn from youtube? I bet it does. Can you help them stand out?Ask your friends about their friends. Who do they know who is in a weird business or industry you're unlikely to know anything about? Maybe they do something hardly anyone knows anything about? I met someone who told me about a friend of theirs who works as a food arranger. For photographing food for cookbooks. She's not the photographer. Or the cook. She's just really good at arranging the food. I had no idea that even existed as a job.So step outside HN and the other places you might frequent online. You might just be able to fix a problem no-one capable of fixing has ever even heard of.
