My introduction to /r/AskHistorians came from a comment onto which I stumbled from /r/All. It was a massive, detailed, three-comment write-up of armored train usage on the Eastern front in WWII.

I never, ever would have thought to ask a question about that subject, but it was a delightful read and I was very grateful that someone asked the question that lead to it. It makes me wonder how many other potential goldmines like that are out there from the passionate contributors on this forum, lacking the question that could lead to their discovery.

Could we have a contained space where someone with a great deal of niche knowledge would be free to talk about it and share their enthusiasm about the subject? The usual rules and standards for sourcing would apply. I might not think to ask, but I would probably enjoy reading a detailed write-up on the methods of elephant husbandry by early Indian farmers or something equally unlikely to come up via standard question.

Actually, although it's a meta post, if anyone would like to talk about the early domestication of elephants, please do so.

And finally if anyone remembers that armored train thread, please post it in the comments because I would love to read it again.
