Today, the buzz on the net is still Ajax.
Now, that was four years ago and it felt like a demo. There was that, ‘this is neat’ feel, but it would only work on IE. It definitely wasn’t smooth, either. It would be a risky proposition to use that technology in a web app back in those days. It wasn’t until the Google suggest demo was out that this stuff was ready to blow people away. Nowadays, both Firefox and IE can pull this stuff off, so you aren’t limiting yourself.
The lesson… stick with it! These technologies eventually find their place, so play with them while they are new. 🙂
