Assignment incomplete:<p>"Before you try to start a startup doing this, however, you should be prepared to explain why existing web-based Office alternatives haven’t taken the world by storm, and how you’re going to beat that."<p>The author needs to deal with this head-on.<p>To some extent he addresses it implicitly by talking about gaining traction the same way Facebook did. This implies that the author thinks that existing web Office tools haven't gained traction because they're too diffusely targeted. The author seems to think that if a web Office tool had a clustered communities of users, this would somehow drive adoption of a web Office replacement. This is an interesting idea, but I think it's inadequately motivated in the writeup. Do college students comprise the right population for these sorts of clusters? I don't think so. I think college students collaborate too infrequently for them to bother adopting such a tool, especially on projects requiring Office-like functionality. If they need to collaborate in this way (once or twice in their career?) they'll just email each other Office documents, or <i>maybe</i> use Google Docs.
