Thumstacks aims to be your prime choice for building and sharing web presentations in your web broswer. You simply create it and publish it, and you will get a link you can share with anyone.
You can even show the presentations in real time over any web browser, which makes it easy for everyone to watch on conference calls or Skype calls. The down side is that you cannot do some basic things like slide transitions or sound or video. So, it seems these presentations are really for real time group viewing or more casual shared presentations. The site offers a forum and development blog.
