PowerPoint for Documentation

Something you might want to consider is using Microsoft PowerPoint for your documentation. The advantage here is the ability to easily share the documentation in a meeting, presented in an community event such as Office365 Saturday, or shared it will sites such as slideshare. So when you do not have to deliver a formal requirements or design document consider PowerPoint.
