Slideshare.net is a beta site (invitation only) that allows people to share easily their presentations with others. Tag them, for others to relate and thus find them, and then present it. It converts from MS PPT and other presentation software into Flash so that the animations are clickthroughs are retained.
You can also embed your new flash presentation into your web page–like on your blog. See! …
I think its a great offering and I’m very excited for when it becomes more public over the next few weeks.
What is nice about it is that like the Author, John Boutelle explains on his own blog, is that you can combine Flash (or other richer RIA technologies, along side standard HTML with or without AJAX) to create a good RIA experience.
