Me neither, but trying a Plexi for the first time (in the form of the Studio Vintage), I understood how a lower-gain, more dynamic amp could be "played".
I've most active on TGP for guitar and Gearslutz for synth. Muffwiggler is more modular-oriented, and VSE is rather slow these days.
I begrudgingly use Facebook for gear sales and a local synth group. I prefer forums, and I'm not even 30. I'm a Boomer trapped in a Millennial body.
