The thing I like most about the fediverse, unlike reddit, is that people are genuinely posting things they care about or like, rather than posting to be a karma whore. I can’t tell you how many times I’ve posted in reddit and it instantly gets stolen and used in another sub simply to get easy karma. It’s refreshing to not have that here. That’s all. Thanks!
I think it’s a combination of all of the reasons you stated AND the sorting algorithm not being the same as some of us are used to on Reddit.
I’m still getting used to finding content I haven’t seen when I’m not toggled to “Subscribed”.
A way to mark something as “read” and not have it show back up for me unless I’ve posted in it would be handy, but as with all new paradigms, I’ll get used to this one eventually and likely wonder how I ever did things the “old way”.
