> Considering only positive and negative ratings (i.e. not a 5-star scale) Is there anywhere that details the changes necessary to use for other rating scales

  You could just convert the 5-star scale to weighted upvotes/downvotes, like so: 1 stars = 0.00 upvote, 1.00 downvote 2 stars = 0.25 upvote, 0.75 downvote 3 stars = 0.50 upvote, 0.50 downvote 4 stars = 0.75 upvote, 0.25 downvote 5 stars = 1.00 upvote, 0.00 downvote And then calculate as usual, and then re-map the result of the formula from the [0, 1] interval to the [1, 5] interval.

  > Considering only positive and negative ratings (i.e. not a 5-star scale) I hate this. It feels like part of the internet getting dumbed down.

    Yes, we should dumb up, not down!
