In the wake of this, I wondered what forums/places people use to ask other people about development/architecture/coding questions and to solicit advice from other developers.
The obvious answers to this seem to have some headwinds: Twitter seems good only if you have a minimum viable amount of followers, and HN always seemed more geared towards news than advice.
I imagine some languages garner more action than others, but I'm not immune to getting stuck in Python or Lisp, and getting really good replies (and occasionally a full debated thread when there are competing methods with pros and cons.) I find showing at least a vague idea of what you've tried goes a long ways there.
Mastodon being the way it is, doesn't work well for searching out those answers since a lot of people delete their posts automagically after a time, so you probably have to hope your question isn't one they've already answered a dozen times recently.
