I've got a mastodon account. The people I follow don't mark snarky quips. Instead, they post updates of things they are making (music, games, and comics mostly); and they share photos that they've taken, and links and comments to news that they find interesting. Compared to Lemmy, it's more personal, because when you respond you are talking directly to a person that you are likely to talk to again.

Mastodon doesn't use a personalised algorithm. So your home feed will only show hashtags and people that you follow. (There is an 'explore' feed for seeing other stuff that might be 'trending' or whatever.) So if you are seeing too many snarky quips - just unfollow the person making them.

It's great for space news. Just wish that would move off X

For years Reddit and Twitter were coexisting peacefully and it should be clear for everyone by now that each format has its pros and cons and they are used for different purposes. Was is a bit interesting though is that the active users gap between Mastodon and Lemmy seems to be much higher than it was/is with the corporate originals.
