I was starting to lose hope when Alpha 5 came out, and was despondent by the time Alpha 7 did. I'm plugging along with the book, half way through the first draft, but at least 25% will need to be revisited to complete examples that hit brick walls because of things just not working as they should, yet, such as custom fields not appearing in the Views sort criteria field list.
I had my ear pierced today. Ow! All right, I concede that on a scale of one-to-ten, the pain measured only two, two-point-five, but that moment when the burly employee in the Claire’s smock assaulted my earlobe with a nail gun, it did hurt.
