I think in part it's that a few Lemmy communities are extremely active / almost spammy and there's no algorithm filtering how much content you get from each place. In the "All" view, most of the content I see comes from the same couple of Lemmy "meme" communities. So it's no wonder most of the content I'm seeing comes from Lemmy when almost all of it comes from two specific communities which are basically meme factories. If I filter those out, there's suddenly a much bigger variety of content from all around and on my "Subscribed" tab I can see plenty of activity from Kbin communities.
You can fix this by subscribing to magazines, and then choosing "subscriptions" in the dropdown menu, or defaulting to subscription in your user settings.
I did this, and only the lemmy magazines I subscribe to show in my feed.
I do this as well and sometimes I switch federation off/on. But I would love to have a way to influence how much a magazine/community pops up in my feed though: by giving a "weight" to a magazine/community that could be accounted for in the ranking algorithm, you would be able to prioritize them. If you like a specific magazine you could give it more weight, which could rank all the posts from that community higher on your feed.
But let's say that I don't want all news clogging up my feed. However, when there is something very big going on that gets a lot of upvotes, I still want to read it as it might be something important or more interesting than the average post from that magazine. In that case I would subscribe to the magazine and give it less weight, so only the highest ranked threads show up.
I think @ernest is already way to busy right now though, but I wanted to share my idea anyway :)
What would be helpful is a page, tab, or dropdown menu that shows subscriptions. Prioritizing feeds would be a nice addition...I wonder if it could be done. But ernest definitely has a full load.
What we have currently is pretty good so far, it's not breaking under the intense load of new users migrating. I'm just happy this is working, and navigation is relatively easy.
I liken this to using a new UI, or OS...you just have to get used to it at first, and figure out how it works. Because I was pretty disoriented when I started using it; people just have to jump in and explore to find things and figure out how it works.
