Corinne Trang, "the Julia Child of Asian cuisine", has an exemplary site: it's highly informative and very elegant, so not only is it easy to find what you're looking for but you also get a sense of what she's about. I still think almost any web presence is better than none at all, no matter what field you're in, but if you're going to do it then you might as well do it right, like Trang has done.
