Stamp collecting is a good outlet for research as leisure. If you're the type of person who falls into wiki holes and likes talking about what you learn with other people, it might be for you.

Many stamp collectors follow the research-as-leisure framework naturally as part of their hobby. The article outlines cultivating curiosity, developing questions, gathering evidence, developing answers, and building communities around that process, which is basically what collectors are doing when they're talking about stamps and other philatelic material. They're sharing discoveries they find interesting, often only after identifying the material, looking up its historical context, drawing parallels to current events, and then formulating some kind of answer or conclusion that makes it worthwhile to share what they've found.

I think the experts in a lot of hobbies engage in this sort of recreational research for the joy of it, but it's closer to the norm for casual collectors. There is a whole wide spectrum of collectors though, ranging from aesthetics-driven folks who spend more time on thematic album pages than on researching anything, over to experts in narrow areas like Transylvanian hotel stamps who publish whole books on about how they weren't valid for postal use but were used by hospitality workers nestled up in the Carpathians to get mail from guests back into the official mail stream because the state couldn't be bothered to service up there. If you get into it you'll find there are a lot of curious and motivated people in the middle who are happy to share what they've been reading about (or listening to, or watching) lately.
