Ok, forget what I said about presentations being boring. Google has now added Presentation to its list of Google Apps. Google Presentation has been panned by reviewers for not having enough tools to create presentations like Microsoft PowerPoint. However, there is one thing I have found that I like if you teach online or have do a presentation where every participant has a computer, the ability to chat. This communication method would be useful for allowing participants to ask questions during a presentation or communicate with other participants. To access this feature you just have to post the presentation and Google takes care of the rest. You will be given a URL to share which you will give out. This could make presentations more interesting by allowing the audience to participate more.
