Lawyers spend a lot of their time reviewing and making edits to documents. How they present those changes to opposing counsel can say a lot about the type of lawyer they are. A multi-colored redline, prepared with the usual comparison software, is pretty standard issue, but keep an eye out for (a) lawyers who only use throwback black and white ""blacklines"" and (b) lawyers who use Word's tracked changes format for editing. The former are anal retentive luddites desperately clinging to the past, while the latter are crazy, sloppy messes who want you to indulge in madness with them. I hope in the future there is some new fun and more beautiful way lawyers can display changes to documents, since those changes in the aggregate become our life’s work.
