The wiki is a multi-faceted beast. It's used to power online encyclopedias and portals that reveal secret government documents. But you know what the very first wiki was used for? A software development hub, birthed 16 years ago today.

Creator Ward Cunningham got the inspiration to create the wiki from using Hypercard. For those who never heard of Hypercard, it was a precursor to the internet we know and love today. With the software, you could make apps that were organized stacks that you navigated through by clicking links. Cunningham loved the structure so much that he ran with the idea, and the rest was history. But even better, you can still check out the very first wiki online today. [Technology Review]
