Slideboom is an online service using which you can easily share your presentations online. Once you upload your presentation to slideboom, it’ll create a slideshow in an intuitive Flash based presentation viewer.
You can use this service even without signing up, but if you choose not to sign up with Slideboom, your uploaded presentation will be removed in a week.
You can only upload Powerpoint presentations(.ppt) and Shows(.pps) with a maximum file size of 30 MB. While uploading, you can choose to publicly show your presentation or not. You can also give an option to your viewers to download your presentation.
SlideBoom is a great tool to share presentations but it lacks support for Open Presentations(ODP) and MS Powerpoint 2007 formats.
