More big news this week: We've launched CodePen into a public beta! It's a site for building stuff from HTML, CSS and JavaScript. Perhaps for yourself to remember later, perhaps to suss out a bug or make a reduced test case, or to show off some cool idea you have. It's all about education and inspiration.

The site was built by Alex Vazquez, Tim Sabat, and myself. We'd love for you to check it out and hit us up with your feedback. We have a vision, but your feedback will help guide it.
