Art Schools and Museums

Why do art schools have near unusable web sites and still purport to teach web design? For an example: School of Visual Concepts

While I'm at it: the Seattle Art Museum has improved their web site over the years, to the point where instead of searching for ten minutes and clicking five times to find out when they are open, I now only have to spend three minutes and click two times. This is information that the Frye Art Museum puts directly on their web home page.
