You need scrape every new-registered domains, extension with .io or filter with keywords, then manually check each newly registered domains, typically, you can find some very new projects or products.
Btw, except ProductHunt and IndieHacker Marshallbananas mentioned, another website that list popular small business ideas, but I forgot its name, damn it.
2. You need to be in a group where people encourage crazy ideas.
HN and the Bay Area have a lot of 1 but not 2. I guess you also have to be somewhere where people don't take themselves too seriously.
A lot of them also seem like crazy fun ideas at first, and often you hear people saying they're just sticking around for the community. You could feel it gain momentum, people get excited and energetic.
Trying to find the next bitcoin like thing will probably be frustrating.
You are looking for things that other people laugh at or dismiss but in your mind will win.

It follows the same rules. Reddit, HN, much of that stuff won't attract people doing big things.
For example, my friend just built a platform with $250k GMV in 3 months. It started with a few back and forth comments on Facebook, and later an invite-only Facebook group. I've seen Minecraft and Dwarf Fortress back when they pointless experiments. Both were popular on forums.

You would still have to reach out to the founders and offer something. Is this what you are trying to do? In this case, how would you approach it?
PS: I also read highscalability.com - the dude usually talks about cool new products and stuff they are making. It's usually heavy tech related but always interesting reads.
I’m not trying to be snarky but if this was easy then what would VCs need to do?
