When you absolutely, positively need to know what something is and you just don't, what do you do? Ask somebody else. Maybe they have more experience with certain areas than you and can bring that to bear.
There's no better place to do that than the internet, and in particular, putting the widely varied experiences of Reddit's r/whatisthisthing community to work. Oh sure, sometimes you'll get jokey replies — because who doesn't like a little fun when the opportunity arises — but for the most part, it's just a group of 1.4 million people who love solving mysteries.
