I have nothing to add to Joel’s moving description, except that it confirms what readers of the TSK books do find to be true: reading the books is itself an exercise in activating the vision.
On the technical issue, Joel, in the “write post” page you should have a row of icons at the top of the section where you right your post that are a lot like Word. To make text bold, highlight it and click on the “B” icon.
Another technical reminder for folks: please remember to sign your posts. (I added signatures to this post and also Peter’s)
