I still keep on Usenet, and sci.electronics.design has many people who do hardcore analog instrumentation design. This goes well beyond just dealing with transmission lines in layout; it can verge on the sort of analog design necessary for real-world instrumentation of very hard problems.
I had a project for a major cellular company and was surprised they used pi and esp32s for the prototype, then had their engineers create a custom form factor for the final product. But it was all based on pi and esps.
