That's what filters are for. For that of course users would need first meaningful (!) tools to curate their own content; instead of just throwing everything onto their profile in chronological order. Maybe some helpful default suggestions that can be renamed and deleted at will, like "status updates", "photos", "big events" or whatever. Even just that without any "subcategories" or "tags" would be enough for a lot of cases, and where it's not, you can put more effort into it. Then it would still up to you as a "subscriber" to decide what of the things you're allowed to see you do want to see on a regular basis; it would generally be up to the user how lazy they want to be, and how much lazyness they want to tolerate in their inbox. Don't tell me it's hard before it was even tried?
