Bought the book immediately, as what we do for a living is third-party JavaScript (search engine for e-commerce, offered as a service).

But I'm surprised to find that there is no mention of Ajax Crawling and SEO (see http://code.google.com/web/ajaxcrawling/), which is a crucial issue, a deal-breaker for many customers. I realize this is a MEAP book, but even the Table of Contents does not hint that search engine indexing will be treated in any way.
