It wasn't too bad when you started to filter out some specific subreddits. But I feel since they applied a lot more content moderation to /r/all, causing a lot of potentially interesting things to not even show up there, it's been kind of garbage for a while now. Something similar can be said about kbins "all" page at the moment too though. I rather wish they'd give the users the tools to tailor their feeds according to their own preferences instead of interfering themselves. "All" should be all, excluding whatever my personal filters & settings get rid of.
