Please have a look. All comments welcome. Some questions:
How should we think about pricing? For instance, as it is, the highest tier of service is quite expensive but allows you to run riot on our server. Is that worth offering, or does it look scary to have that big dollar amount on the signup page?
Draftastic sounds a lot like Google Docs, but it's quite different in practice. (GD is like a whiteboard; we're like a revision control system.) Should we worry about making that crystal clear up front, or does it look weird to define ourselves that way to new users?
Given that it could be marketed to practically any kind of business, what are some good sorts to concentrate on? Where do we look for people stuck in the mail-a-Word-file-around groove?
How can we persuade more casual visitors to try it? We made the free signup process as easy as possible, but it's still several clicks. Is it worth trying to maintain an open sandbox? Does a sandbox even make sense when we're designing for cooperative groups?
