Hi Polonus,
It is a nuisance to see so many websites using jQuery, especially since JavaScript 5.1 (ECMA-262) handles many (if not all) common selectors and event handlers that jQuery uses. It's been around long enough to have full support in all modern browsers (even IE9, sans strict mode), and the extra blob of code formed by jQuery could be removed and replaced with native JavaScript methods and properties that are not only faster, but may also be more secure in some cases.
