and it is often met with derision. I used to post on G+ 3D printing but gave up after people complained that the solutions I was posting to problems were all too expensive for people to try despite providing links to inexpensive parts sources and demonstrating the principles I espoused with video, photos, and measured data.
Years ago I developed techniques to fabricate electrostatic loudspeakers very inexpensively and was active in DIY audio forums. It became so ridiculous to try to provide useful info against the people who were shouting about cables and magic rocks, polarity of resistors, and other BS, that I finally gave up.
America has been dumbing down for decades and elevating stupidity to high art. We are stupid and we deserve whatever the politicians we elect do to us.
I'm building my 3rd and last 3D printer now and will soon abandon the forums and move on to some other endeavor.
