The number would need to be much higher than 10. This is not a problem with demand, no. It is a problem with geography. Google Wave is available to more than 10 countries. For this scheme to work, with a reasonable response time, we would need at least one or two people per country (depending on country size). Other than this impracticality, I like the idea... It would also require people to have gps tracking turned on so the Google people could find them...

SharePoint is not the most elegant or user-friendly system ever made. I have used it now at work for a few years, and it is used a lot, and does a lot, but nothing is fast or simple to use. New and current users require a lot of training. It doesn't seem to do anything very well, simply because it tries to do too much. It will integrate with Microsoft Office and you can embed InfoPath forms etc, but it never seems quite as integrated as the documentation suggests.
