I am old and my nerdness has worn off over time. I prefer to hang out in person *) with people like me. I have a "regular's table" for UNIX and Linux admins and most of the tech questions i am interested in are discussed there.

Speaking about tech questions: 30 years ago i was interested in things like how to save a few CPU cycles in an echo canceller on a DSP but today i am more interested in "strategic" things: how to most efficiently run datacenters, DevOps methods, etc.. Such topics are less a matter of "factual know-how" but more driven by paradigmatical issues and generally "soft issues". Internet forae rarely have such topics, probably because there is no "one true answer" to such questions. If i want to know "how to change this format into that" then there are at best a handful of ways and all of them can be tested to either work or fail. A question like "how to organise a data center" is answered by something that is much less "true" or "false".
