There are literally thousands of people “chucking pollen” at any given moment. It’s rare to find people who just work a few lines for years or decades.
@Cannabian provided a lot of good info. I could add to that, but I strongly suggest you buy a few books on breeding; Greg Greene, Robert Connell Clark, and DJ Short all have excellent and affordable books.
I’m not saying you shouldn’t make seeds, but I do think you should do it with clear purpose. If you want to make exceptional seeds, you should start by growing different cultivars, decide what qualities you value, and then start selecting from large populations toward your goals. I don’t know of any location in the states that afford people the protection to do that legally.
If you really want to be different, collecting landraces is a good place to start. I’d also look for some foundational breeding stock; in other words, highly domesticated cultivars. But if you can acquire authentic landraces, you’ll bypass many of the genetic bottlenecks we see in popular cannabis cultivars. You’ll also have some interesting challenges as you try to make those “wild” plants work for your environment.
