Bought the book immediately - I don't think I've ever bought something so quickly! This is a book whose value is very clear - if you're working in the field of embeddable widgets (as I am), you know how "hack-ish" and tricky a field it is. The Disqus people have managed to make a great product despite this - any tricks I can learn from them that will make my life easier will be worth tons. I agree with jwr - SEO is a big topic which I know nothing about, except feeling vaguely uneasy since I know we're losing a lot of SEO opportunities with our widget. Definitely a topic that should be covered in the book. This might be a niche topic, but how about talking about advertising inside widgets in the book? Advertising is a method that many widgets use to monetize, but I'm unclear how well the standard Google adwords, etc. solutions work with embeddable widgets.
