The thing is that I am kind of sad, because my post/comment wasn't meant to bash O'Reilly but point out how unexpected use cases and unplanned events backfire if they aren't properly handled. It turns out O'Reilly was actually having a planning meeting today to work on their new ecommerce website system.-tinjaw
Don't be sad. If you hadn't posted on your blog:
1) You would never have gotten the great deal on the books you will now enjoy.
2) O'Reilly may never have caught the bug in their shopping cart system.
3) Others who want(ed) the same deal wouldn't be able to enjoy the great deal, either.
Rejoice. Your blog post did a lot of good for a lot of people.
