Interesting.

Complexity theory, and what happened to Yellowstone. Sent to me by my brother, and an interesting read. I'd love to see someone apply it to the accountability drive in education.

Another vaccination debate.

I did enjoy this one. I am continually surprised, however, at how people who have been reading booju for several years still don't know or appreciate things like the value of herd immunity or that vaccinated kids can still get sick. Vaccination is one of the few parenting issues where not-my-kid-not-my-business doesn't apply, because every unvaccinated kid increases the likelihood of an outbreak, the likely severity of that outbreak, and the effectiveness of everyone else's vaccines.

I have no problem with people looking at all the facts and deciding to selectively or delay-vax, especially in the States where kids get an obscene number of shots at each visit. Delaying a few months or a year or two probably isn't going to be an issue, and if you feel better about that for your child, so be it. I'm also okay with people choosing not to vax one child who has medical problems. But I really believe that failure to vaccinate most kids within shooting distance of "on time" is a public health risk and a bad idea.

For pet lovers with a bit of spare change
