No, AFAIK, Google does not run Javascript code first without special accommodations. See https://developers.google.com/webmasters/ajax-crawling/.

There's a fundamental disjunction between today's search crawlers and these kind of dynamic Javascript apps that's just going to become even worse.

If anything, I think libraries like OJ point out the disjunction and therefore encourage discussion of what the future should be. HTML and Javascript have served us admirably, and given the nature of the web one wonders if we will ever get away from these technologies. That said, using one in isolation without the other (i.e. Javascript to generate HTML but not writing HTML) diminishes both as far as the usefulness of the "web" as we used to know it, at least.

I might even go so far as to say that fully dynamic browser apps, without the proper functionality for search engine indexing, are a direct threat to the business model and usefulness of search engines.

I'm sorry, but you are incorrect. It may not be officially supported, but they are doing it.

https://www.google.com/search?q=uiji.js

Check out the results for the 1st link (aakilfernandes.com/uiji.html) and then check the source code. You'll see that the entire body of the page is written with javascript.

I stand corrected - sort of - a bit more research shows the reality is "some dynamic/Ajax content" is indexed by Google, and not all search engines (i.e. Bing) are doing it yet.

For example, same search on Bing - http://www.bing.com/search?q=uiji.js
