My initial thought is definitely yes for the Steam Machine, and maybe yes for the Steam Frame.
All devices are Valve made hardware running steamOS, so I would think a lot of the discussions/content would apply to Steam Deck. This also isn’t a super busy community, so I wouldn’t be that worried about Steam Deck specific content getting buried.
The Steam Frame is a bit more iffy than the Steam Machine though, there’s a lot of experience differences between the Deck/Machine and a VR device, so there will be larger differences. Also the Frame has ARM hardware and has to use an additional x86 to ARM compatibility layer for games running on it, so we’ll probably see some unique compatibility bugs for it.
Overall though I just want to hear everyone else’s opinions on it.
I’d say yes. If the volume becomes overwhelming new communities can easily be created.
Agreed, the fediverse is small enough now that living aggregate communities are preferable to dead specific ones. Especially because everyone hates posting something, getting their post removed and being told to go post in another very similar community they didn’t know existed. As you said, if it becomes a problem you can just spin off
Fragmented communities is such an annoying problem in the fediverse.
The problem can also be a positive, so that communities for more specific niches can be created, or to have alternatives for already existing ones with different management philosophies.
