@jonhoo may I ask you why you select `mastodon.at` among other hosts?
@alishir I did a bit of digging with https://instances.social/; I wanted a host that had A+ TLS and from the observatory, that was kept up-to-date with upstream Mastodon, and that was opinionated about moderation (e.g., no Nazism) without being too restrictive (e.g., no nsfw). mastodon.at seems to be well managed, has a good ToS which moderates highly toxic content while generally being liberal about what content is permitted. It's also large enough that it's unlikely to go away :) /cc @pfigel
(Regarding the single-column thing, you might enjoy Pinafore's UI! We have an instance running at https://light.mastodon.at/, or you can use the one hosted by the creator at https://pinafore.social/).
@pfigel Oooh, Pinafore looks like exactly what I wanted — thanks! Bus factor of 1 is unfortunate, but I'll take my chances with it for now ;)
mastodon.at is a microblogging site that federates with most instances on the Fediverse.
