There's a reference to one of the 'value-add's of commercial journals being copy-editing:
> "For example, most of PLoS ONE’s editors are working scientists, and the journal does not perform functions such as copy-editing."
But, in fact, in my personal experience, the for-profit journals don't really do copy-editing anyway, but in fact introduce new errors into the paper which then the author has to pain-stakingly track down (or not).
