Ask PG: Why are submission titles manipulated without notification?
There's a guideline that you're not supposed to editorialise titles. When an editorialised title is detected, it is usually corrected.I happen to disagree with this policy and I think it's a somewhat overly rigid application of the guidelines. However, this is why it's happening, and it makes some sense from at least one perspective. And, after all, this is entirely pg's call to make.
