On the flipside of that is perhaps the geekhack forums, with a ton of elitists that sometimes have little patience for people that are not up to speed.
The forums I find worse are /r/mechanicalkeyboards on Reddit (elitist about customs) and Deskthority (elitist about vintage, and also unmoderated) For mech newbies, I have found various PC-hardware forums to be the most welcoming.
(Unrelated, my personal story:) As is my habit, I got real into researching MKs for a few months, went through 2 (one I liked pretty well but I really missed dedicated home/end keys, and one that had switches that were slightly too tough to push and thus I kept missing letters) before I found my dream one: Mistel MD770 with MX Browns. It’s a split that I can shift around however I like. I love it. Oh, and to finish what I was getting at, as is my habit I can now stop thinking about MKs and will soon forget most everything I learned.
