My preferred way to browse here is using All and blocking communities I don't want to see. That way I get exposed to new things I wouldn't seek out on my own (for example: British archaeology)
I accidentally blocked a community while trying to block a user and when I went to unblock it, I saw I had 1250 communities filtered. If I had to guess, 90% are either porn, sports, or anime.
Running out of content to browse is not a bad thing in my view. Then I just go do something else.
Even on my subscribed feed about 5th of the threads are caught by my daily growing list of content filters. I lose nothing of a value by filtering out the noise from the signal. Still waiting for someone to come up with uBlock filter to block threads linking to specific websites.
