Periodically I like to scan the blogosphere to see if there are any presentation or PowerPoint blogs that I haven't tracked down that might provide some valuable insights. One of the latest that I've identified is the VisiScience Blog, that discusses the use of PPT in science. They have a number of tutorials that might be useful for those of you using PPT for this purpose. The blog appears to be published by the sellers of ScienceSlides a vendor that provides a module for scientific slides.
Do you have any recommendations on PowerPoint or presentation skills blogs that I should be tracking?
