In particular, I'm subscribed to no general-purpose or wide-purpose subreddits. A few city/geographic subreddits mentioned it in passing, but, like, /r/programming or /r/nycbike or /r/radicalchristianity are going to treat any post about it as off-topic. You can't just post an advice animal about it, or request IAmAs from everyone involved, or say that today you learned whatever-it-may-be about Ellen Pao, or what have you. Nor can you do this about any other topic, which is why I bother to read these subreddits.
Then on r/all NSW/offensive are disabled by default (the same way NSFW is rigth now - you need to change your account settings).
Problem solved, FPH will never make it to people who don't want to see offensive staff.
And even among technology, I have no interest in seeing things about Ruby or Go. Again, it's not that I dislike the languages, it's that they're not professionally relevant to me at the moment so it's not what I visit Reddit for.
So what we need is some way for subreddits to be tagged with their own content: /r/rust about Rust, /r/python about Python, /r/sandersforpresident about Bernie, etc., and some /r/all equivalent that just matches what I'm interested in -- which is exactly what https://reddit.com is for me, right now. I don't need /r/all to be fixed; I have no interest in even seeing "all technology" or "all religion" or "all presidential candidates".
FPH being or not being on /r/all is irrelevant.
(I echo the comments that say that Reddit has great subreddits like /r/Haskell and it's easy to mis all of this when you are just subscribed to a few subreddits.)
