CQuery is directly colliding with Yahoo's YQL (<a href="http://developer.yahoo.com/yql/" rel="nofollow">http://developer.yahoo.com/yql/</a>, look for "CSS Selectors"), which was there loooooong before cquery.com was even registered.<p>Idea about "tracking changes on pages" was there for ages. For ex. <a href="http://searchenginewatch.com/3574636" rel="nofollow">http://searchenginewatch.com/3574636</a> (Jan 2006)<p>You won't convince Google to change anything. It's still "Go" language despite huge PR coverage and years and books behind other "Go" language.
