The headline of this post is a gag of course, but I was surprised (pleasantly) to see that the 2006 In Your Words "time capsule" as some are calling it, has been featured as a "popular" item in slideshare. If you haven't used slideshare yet, it's eerily similar to YouTube, except it's designed for us PowerPoint Jockeys. It's not perfect (doesn't render flawlessly), however it's terribly effective, easy to use and a nice alternative to e-mailing large presentations (or a collection of photos). And like You Tube, it turns what you upload into a social, open source piece of content designed for distribution.
So, if you are comfortable with working in a presentation format and feel like sharing, take slideshare for a test drive.
