This is the only place I’m aware of, but I’ve hardly done a thorough search. There are some fediverse/lemmy community search tools out there you could probably hit up. One thing that’s most likely true is that there’s no official QMK community on Lemmy.
Been using a ZSA Voyager as a travel keyboard for work and very satisfied with it. Used a Sofle V2 prior to that but I was concerned about how well it was (or rather wasn’t) holding up to the rigors of travel so I replaced it with something designed for travel and a little more robustly constructed.
I use a Workman layout and a few years ago switched to using homerow mods so I found the modifier keys on the Sofle to be redundant so I decided to downscale to something a little more compact. Because my usage is for work the number keys get used heavily so I wasn’t willing to give those up by going to something like a Corne. On the flip side I wouldn’t use the Voyager for gaming due to those same missing modifier keys since keys like shift and ctrl are used in a non-modifier pattern when gaming.
