A New Vertical Called Workstreaming
Web Worker Daily has written a post where they describe the Lifestreaming concept specifically for providing updates in regards to work for co-workers and such to track what you’ve been working on.
“Workstreaming is the next generation of the 11 pm email you send to your team to show them that youâ€™ve been working all evening.”
Seems like a decent vertical approach to the concept if the tools you use for work could provide such information. I can see where MS Office Apps could provide an RSS feed for snapshots of the progress of documents you are working on.
