It's easy to use, it has all of your tools in one place (revisions included), you can get feedback from other people working with me at any time - great for revision! I dislike that there isn't an option available if we're collaborating via email or chat/IM rather than using our actual accounts which would allow us more control over who sees what information when etc., but this may be something specific only affecting my account as opposed others' experience? We've been able solve almost every problem together by just sending eachother files back-and forth through Dropbox; sometimes though they are not synced properly so need another round trip before everything works perfectly again :) Having access 24 hours throughout day makes collaboration much easier too since everyone knows where their work will appear next without having anyone waiting around forever while someone else finishes up editing first.- The ability collaborate easily across different platforms like iOS vs Android devices.
