I agree Keen, but people like Abom79 and Oxtoolco, NYCCNC even Mrpete222 make good money from YouTube. I don't do it for money, but the money buys some endmills each month and I have fun doing it. I guess since I work for myself for a living, you try and make money anywhere you can. Hirudin would probably make about $50 a month I'd guess. That is still a couple endmills.
