So I just had an idea yesterday. There's a youtuber that I used to watch to broaden my perspective about (never mind...)
So here's the idea that I tried. I looked for one of her videos, and tried to find one that had a very club oriented nature (example: "why I dressed like an indie girl")
and I just copied the title and did another search with the exact same title. So from the results, I could see that many people were the same type (or at least same club).
And it drastically improved the likelihood of finding people of that type (let's say about 1/4 of them were the same type).
From this, one can easily apply this idea to finding any type anywhere. I'm going to test this idea with real life people and enjoy the beauty of it.
