Jakob Nielsen in a Builder AU interview:

"We could look beyond [cloning] and there could be a new set of productivity software. It could really be done another way. The real problem with Microsoft Office, besides being Microsoft, is that it is an office product based on paper. It comes out of research about how to do office automation.

In the new world what we need is not memos but we need to build Web sites and intranets so when you communicate in companies it is via a collaborative environment. Some areas where they have had success is in Wikis and some of the blog software, but of course it is still quite primitive. But you could make something quite more interesting based on this on things like intranets."
