Mark Guzdial's blog is a great discussion point (in general I think Mark's blog is really good but he has slipped up here). Alan has left a comprehensive response there, which does refute part of what Mark is saying
His basic point is right, even if two of his examples are wrong. The problem I've had with design patterns is that they're not all that meaningful until you've had to build them, and once you've built them, they seem fairly obvious. I've found them more useful for communication than anything.
In contrast to his point about Etoys, the problem I've had with them is that they're too concrete.<s>
