I dunno who can read this, but here's me saying hello from my dandy RPi Model B with #NETBSD with the #nanotodon minimalist client!
And now I can also do it from the #toot client!
It's not the fastest client around, given Python's overhead, but at least it's definitely the most complete so far.
It looks like there's also #Mastodonochrome, a TUI client written in rust, but I don't think there's a package in NetBSD for it
Bitslingers-R-Us@kzimmermann rust-bin is available for earmv6hf, so it should be doable.
It seems that it’s not in pkgsrc yet, though, so you’d have to compile it yourself.
