Ability to hide own post from some feeds
Feature suggestion: Make it possible to "hide" a post from one or more of the feeds. If hidden from all three, it would only appear on your own profile page.
This would be useful when people have a post that is only really relevant to some subset of people, and as a result are hesitant to post it.
It would also be useful for posts which unexpectedly become huge arguments. Rather than deleting the post and risking annoying the other participants, and rather than leaving it where it is as a stain on the newsfeed, perpetuating the dispute, it could be quietly tucked away on your profile page.
