The two aspects of editing I enjoy the most are learning about the subject I’m reading about and constantly improving my own English as I do so.
Notice I didn’t include formatting reference lists. That work, however, is time consuming and, hence, pays well. Yet I’ll gladly give up the billable hours for papers that have the reference lists formatted correctly.
I haven’t tried either application yet, but will report back after doing so. Using them will make my job easier and save my clients money (although it’d save them even more money if they bought the software themselves).
