In those two cases I’d think the Friendica/Hubzilla apps and the Lemmy/K-Bin apps would fit those two needs respectively. I’ve also bookmarked this thing called Fire fish that seems to have potential as a sort of all-of-the-above effort that could prove interesting, just don’t want to see something that tries to be too much at once and fails at all of it as a result though.
A big part of the problems in anything on the fediverse as a professional presentation is that very little of the software is really well polished. Mastodon is probably the most ‘pretty’ of any of them right now that I’m familiar with, but there’s always the balancing act with new software between working well and looking good/friendly that takes some time to hammer out, particularly if there isn’t a massive development team backing it.
