I am a fan of SlideShare, a website where you can share your presentations with the world. There are some really helpful presentations at the site, you can pretty much learn anything you want — just use the search function for your favorite topic.
So I was thrilled to learn that they are having a contest for the World’s Best Presentation and they are offering some really cool prizes. You can go to the website and check out the rules. Here’s a SlideShare presentation about the contest too.
