Apple adds 100-person collaboration to iWork, takes aim at Google Docs and Office Online
So if you're on a Mac and not already using Microsoft Office for Mac, then you might be one of those (less numerous) iWork users. You're in luck then if you're using iWork for the Cloud, then Apple has just updated its suite to support 100 people.
Now why would you need 100 people or contributors on a single document? Sounds rather crazy as 100 people working on either Keynote, Numbers or Pages at the same time on a single file sounds like a nightmare. But perhaps Apple knows something we don't or even received a request for such a crazy update.
