It is always fun (in a broad sense of that word) when I make a comment on an industry I know nothing about and somehow stumble onto a thing that not only has a name but also research. I am sure there is a German word for that feel of discovering something that countless others have already discovered.

Any time I invent a cool thing, I go and try and find it online. Usually it's already an established product, which totally validates my feeling that the thing I invented is cool and would be a good product. :D
Occasionally it's (as far as I can tell) a legitimately new 'wow that's obvious' style thing and I consider prototyping it. :)
