I built a wireless Kyria keyboard late last year and love it. I went with LEDs and OLEDS (not recommended, I basically have to leave both halves plugged in if I want to use them).
They are a lot more comfortable to use than a standard keyboard IMO.
Ahh, I didn't get that far in the docs, but seeing as there are no (that I can tell) post limits, running a blog on Lemmy would work pretty well with a bit of a UI change.
Trying my best! I'm trying to decide if I want to open my instance up to more users or not as well.
