I am working on a business proposal using Google Docs right now.  As I’m editing that proposal, someone else in the company is editing around me, making changes to other sections, reordering the document, doing all sorts of crazy things, and it isn’t interrupting my workflow.  Occasionally I’ll notice some text move around, but aside from that, I’d swear that I was working alone. 

Word has some nice finishing features, but for managing a shared document, Google Docs FTW!
