Fully agreed – it at least seems like you could tune for this in your less deterministic algorithmic sorting, too. There's no Reddit Constitution that says an upvote is an upvote is an upvote – so you could weight upvotes issued from people viewing the subreddits' pages more strongly than those from people viewing their home feeds, upvotes from subscribers' home feeds more strongly than nonsubscribers' /all feeds, etc. etc., downvotes mutatis mutandis
