I'm having somewhat of a writer's block, both here and in other writing I'm doing. Unfortunate, since I got linked by IHE. First, I think you should read what Profgrrrrl has to say about this whole linking by them thing. I didn't know I'd been linked until I read it in the comments there. Obviously, I'm not paying attention. You should also scroll down in her blog and see the comments to this post. And Jill writes about it too.
If you're here from IHE, put the post in context. There are other, better posts on the same topic. And you know, I'm a a human being, so there's other stuff here too.
