From the Official Google Blog:

today we’re unveiling the new Google Docs presentations feature and invite you to try it at docs.google.com. Maybe more than any other type of document, presentations are created to be shared. But assembling slide decks by emailing them around is as frustrating as it is time-consuming. The new presentations feature of Google Docs helps you to easily organize, share, present, and collaborate on presentations, using only a web browser.

Starting today, presentations — whether imported from existing files or created using the new slide editor — are listed alongside documents and spreadsheets in the Google Docs document list. They can be edited, shared, and published using the familiar Google Docs interface, with several collaborators working on a slide deck simultaneously, in real time. When it’s time to present, participants can simply click a link to follow along as the presenter takes the audience through the slideshow. Participants are connected through Google Talk and can chat about the presentation as they’re watching. Not wanting anyone to feel left out, we’ve made the presentation feature available in 25 languages; Google Apps customers can also access it as part of Google Docs.

I haven’t tried it, but it sounds worth a check-out.

Cindy at CindyAE asks an interesting question: What would you do if you had a celebrity among your attendees? I personally would try to treat him or her like any other attendee, but what would you do if others started bugging him/her for autographs, or his/her presence caused problems just by virtue of being a celebrity amongst us mortals?

I’m not sure how I’d handle it, but I can see how it could get strange.
