Very valid and pertinent point, Manish. Thanks for bringing it up. We are looking at some solutions to make the pages lighter, and faster to load. However, currently we are not in favour of making the content dynamic/ajax. Most content on this site is static in nature, so as to keep the pages structurally simple (albeit heavy) cater to the widest varieties of computers and browsers.
We are working on it, and shall update everyone when we have something ready. Thanks again.
