A couple of weeks ago, we added support for embedding RockYou slideshows. The feedback has been very positive and people have been requesting more slideshows, in particular ones from Slideshare.net and Slide.com.
Slideshare is a great service that enables the sharing of PowerPoint and OpenOffice presentations. There are lots of interesting presentations on their site and you can upload your own and then embed them into a blog post or page via a simple shortcode that’s listed next to all of the presentations on their site.
Slide.com allows you to upload photos and turn them into a slideshow which you can then embed into a blog post or page. They have created a nifty link for us that lets you create a show and then embed it to WordPress.com when you’re done. We also support Slide.com guestbooks in a similar fashion (they allow your friends and readers to leave photos and video comments).
