Balisage: where serious markup practitioners and theoreticians meet every summer. If you are happy to be the person in your project who understands the angle brackets and stuff, then you are a markup geek and Balisage is the place for you. Even if you are NOT a markup geek, if you find it instructive to spend time with them now and then, you will enjoy Balisage.
