Felipe Voloch calls the introduction of a service by which one pays Elsevier to fix the English of your article “a new new low”. This wasn’t my reaction at all, and I was curious what people thought of this.
My initial reaction is that this is how capitalism is supposed to work: people need a service they cannot provide for themselves, and so they pay someone to do it for them. I honestly don’t see how else the English of scientific articles (which is of quite uneven quality) is going to get fixed. It’s not the referee’s job to so comprehensively, and while it would be nice to think this could be handled by informal networks (which is essentially what Chris Brav suggests) this doesn’t seem to be happening.
Now, I could easily imagine that this is not actually a good service; my experience with copy-editors working on my accepted papers has not left me all that impressed but I don’t see why it is a priori problematic.
