One of my favorite things about iWork from Apple was its ability to share documents online for review and approval. It made it very easy to control access of clients and give them a unique login to view and comment about what you were posting. Whether you were collaborating with a team or just needed secure delivery, the service just worked well.
So of course, Apple just killed it.
Last year, we launched iCloud, a service that stores your music, photos, documents, and more and wirelessly pushes them to all your devices. Today, there are already over 40 million documents stored on iCloud by millions of iWork customers. Learn more about iCloud. With a new way to share iWork documents between your devices using iCloud, the iWork.com public beta service will no longer be available. As of July 31, 2012, you will no longer be able to access your documents on the iWork.com site or view them on the web.
Apparently, no one explained to them how the two services were different. It's the same sort of logic which killed iChat in favor of iMessage (which of course doesn't integrate with GarageBand for group recording, let you share your screen with another user, or collaborate on a file interactively.
Be sure to sign in to iWork.com before July 31, 2012, and download all your documents to your computer.
