Today, Google Docs released the ability to create Presentations (PowerPoint-esque slideshows).
Create a whole new slideshow in Presentations or upload an existing
PowerPoint file to get started. Kick your web-based presentation into
slideshow view mode and invite others to see it real time as you move
through slidesâ€”with chat built right into the sidebar. Make the
slideshow public or invite specific collaborators to edit and/or view.
Online presentation with real-time chat? Sounds pretty nifty. Look out, PowerPoint!
