SO is initiating the trial of a new feature, the “Staging Ground”.
This effectively acts as a review process that occurs before a question asked by a new user appears on the main page. It’s something we, here on EL&U, have mulled as a way to improve the quality of the stream of questions we get on a daily basis.
Now, this is in the very early stages, and will initially apply only to SO. But like other quality control mechanisms that initially start out on SO (e.g. moving from 5 VtC to 3 VtC), it might eventually make its way to our little site¹.
Anyway, something worth keeping your eye on.
¹ Of course, that’s only possible if the experiment on SO is considered a success, and even after that I wouldn’t expect it to be rolled out to other sites quickly - I’m thinking a year or two here.
