I would rather see a sort/feed option which limits the number of posts shown from each individual subsciption (e.g. max 3 or 5 posts) and also have a “See all from [subscription]” button imbedded. I know that there is an enhancement request in to change the algorithm for top (or hot?) categories to take/order the the #1 ranked post from each subscription followed by the #2 post from each subscription and so on… which may help a bit.
But, frankly, I think we should just ask XKCD’s Randall Munroe - he came up with Reddit’s HOT sort and definitely has more insight on what drives a good algorithm.
