Stack Overflow has recently unveiled the Trending sort option, that weighs votes cast recently heavier than those cast earlier, in order to promote fresh answers showcasing new techniques over stale answers based on outdated technology.
Though I was rather sceptical initially (and I still hardly consider it perfect), I think it could mitigate at least some cases of the FGITW problem, especially on sites where scores are prone to being biased by drive-by HNQ votes. Trending sort could weigh votes accumulated organically heavier relative to those received when the question is fresh, while in HNQ.
Is there a plan to introduce this sort option to other Stack Exchange sites?
