I’m not sure if ‘unsubscribing’ is an issue for members. It’s really very nicely done. I can now scroll through screens which are nothing but stories from people I follow. Or publications I follow. Or stories people I follow recommended. Membership does not so much get rid of the crap, as collect the crap in a corner for you which you can then easily ignore. I’ll need to do a little more tweaking in terms of people, publications and tags I follow to get the most out of it, but so far I do not regret getting it in the slightest.
