At first, Mary Beth and I thought we were the only people on Blogger blogging about the Enneagram. We checked out www.enneagram.blogspot.com, but it's just a blank page.
Still, it turns out we're not alone. The aptly named "The Enneagram Blogspot" is, in its own words, "a compilation of several different Enneagram personality theory resources."
The material there does seem to be compiled from various Enneagram books and websites, so it doesn't have the, ahem, charm of two gals yakking about the Enneagram and whatever else catches their attention every single day, but still, there is a wealth of good info there.
I especially like the article "Enneagram and Terry Pratchett", which has pictures and gives the types of various characters from the Discworld novels.
