This is something that happens on reddit too. If you follow a sub that it active but not hugely so their posts will get absolutely buried in the massive flood of bigger subs.
This isn't really something that can be "solved". If you follow one sub that gets 1 post every hour and 10 subs that each get 1 post every 6 minutes. This means that for every 1 post in the small sub you get 100 posts from other subs. That's four pages on reddit to go through to find 1 (!) post.
Say you want the last 5 posts from your tiny sub. Those are going to be spread somewhere through 20 pages. The only way for the software to bring them closer together would be to omit (large) parts of the other content streams. This would mean THAT content gets burried instead.
The solution is to recognize /r/lamaswearingpinkhatstothebeach simply isn't going to post often enough to show up next to /r/aww and browse them directly.
One possibility would be to auto group streams of similar productivity together so you'd have a "frantic" main feed, a "busy" main feed, a "composed" main feed, a "chill" main feed etc. however many are needed. But you'd still have to deliberately browse each individually.
