The tagline (tag-paragraph?) is a little opaque:<p><i>A simple way to build web applications with embedded server side JavaScript. In a few minutes you can build dynamic backend logic in to any page (html, css, etc) using node.js, jQuery and server side DOM with php-like embedded code.</i><p>Having read through the rest of the page, I'd rewrite it like this:<p><i>A way to embed server-side JavaScript into HTML and CSS files. JSPP uses PHP-like template tags and gives you access to jQuery and node.js modules.</i>
