If you are working with WordPress in any capacity, you have to watch this talk. Or at least the first 25 minutes (before the Q&A). If you are involved with web publishing or web design, you have to watch it. If you are a web enthusiast, you have to watch it. If you are not involved with the web at all, you definitely have to watch it, as you’ll have an idea of where things are going, and you might decide to get involved.
Just watch it!
