Right.

By the way, the whole idea of Ajax Crawling as defined per Google struck me as wholly unnecessary. If you are using unobtrusive JavaScript, and HTML like so:

    <a href="http://twitter.com/ev">@ev</a>

with JavaScript adding a click handler such that a user’s click on the above link actually only triggers an AJAX deal (FWIW, jQuery stub:)

    jQuery('a[href^=http://twitter.com/]').live('click', function(){
        // Do AJAXy thing instead, then
        return false;
     });

Then, assuming you serve up essentially the same content at /ev that you would display via AJAX, you have simultaneously just enabled your site for not only modern browsers, but also robots and dumb phone / JS-avoiding users. (And middle-clickers.) No goofy API required.

Edit I just realized, if you have links to `http://twitter.com/#!ev` in the wild, then the AJAX crawler thing becomes actually pretty useful.
