The story in this game sounds so interesting, and it’s so well written and voice acted. And wow, this was made by Bungie, I’m surprised it wasn’t mentioned in the video. The music in the intro really reminded me of Halo music, so that makes a lot of sense.

You need to view your subscribed communities, they’ll show up there. By default it’s probably either showing Local or All.

Everything except for the UHS-III part, yes. Some UHS-II stuff exists, but I think it’s limited to full-size SD cards right now, and the Deck only has a UHS-I bus.

The SD Association has this page explaining the speeds, and from what I can see, it’s just to guarantee speeds with certain bus types. Most devices currently use a UHS-I bus, and the older speed classes cap out at pretty pathetic numbers, so they’re kind of useless. For the steam deck, any of the higher-end cards are going to be about the same, and the IOPS are going to be more important in terms of loading times anyway.

2TB cards don’t exist quite yet.

The SDUC standard exists, but no, there aren’t any commercial 2TB microSD cards yet, though they’re coming.

I didn’t make posts all that often on reddit, but I definitely commented a fair amount. The problem I’ve got with lemmy right now is there’s not as much discussion about stuff I’m interested in, so I’m mainly just looking at All instead of keeping to my subscribed communities.

I haven’t been having issues with my lemmy.world account, other than the occasional slow/failing to load page, but that gets fixed with a refresh.

I’d say separate. You can only interact with the other instances through your instance, and while they use the same protocol, lemmy and mastodon are just fundamentally different styles of communication that don’t mesh well together.
