SlideShare is an online presentation sharing tool. You can add your own presentations in PowerPoint, Open Office or pdf format. And you can share these documents publicly or privately. In common with other Web 2.O applications you can tag your presentations with keywords of your choice and post comments.

This is also a great tool for digital storytelling. SlideShare have added the ability to add your own audio files to your presentation and it provides you with an online sychronisation tool to match up your audio with individual slides. One slight niggle is that you can’t embed the audio with your presentation. The audio file has to be hosted elsewhere.

I’ve made a quick example showing you how it can be used for instructional purposes. I took some photos with the camera on my mobile phone. Transferred the pictures over to my laptop. Stuck them in PowerPoint. Plugged in a mic and recorded an audio track in Audacity (open source audio editor). Uploaded the PowerPoint to SlideShare. Uploaded the audio mp3 file to our webserver - this can be any publicly accessible place on the web. Clicked on the edit button on SlideShare to add a “SlideCast”. It then took me to the synchronisation tool so that I could line up my audio with my slides. Then clicked on “publish”. And that was it. This could be great tool for digital storytelling. And it’s also easy to share your newly created slidecast on your own blog. I’ve copied and pasted the code provided by slideshare and pasted it below. This is slidecast details my portable field recording/podcasting setup. Click the play button to hear the audio. You can aslo skip through slide-by-slide using the forward and back buttons.
