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 :)
