The hotness score of a question is influenced by the reaction of users arriving from across the network. Since most of such users do not have 125 rep on the question's site, the feedback SE receives is one-sided: the algorithm hears those who like the question (via upvotes), and ignores those who do not like it (they can't downvote).
I propose that negative feedback be collected as well: when a user with 15+ (or maybe 101+) reputation on question's site clicks the down arrow, this feedback should decrease the hotness of the question.
This proposal is somewhat similar to Logged in users with less than 15 reputation should be able to give feedback, but differs in the following:
- proposes collecting negative feedback from <125 rep users, not positive feedback from <15 rep users.
- proposes using the feedback in the hotness formula.
The hope is that more balanced feedback would result in better selection of questions that are of genuine quality, not merely accessible to many.
