What do you think of single page websites?

Single page websites are powerful. All the content is there and readily available. As far as information consumption, it's a great way to get the info across. However I like a different type of single page site. AJAX SITES!!! I absolutely fucking love AJAX sites. You can send the most important data first, don't waste data on stuff people wont notice at first. If they wish to engage further, more data is loaded. Saving fucktons of bandwidth in my experience. My old site was single paged without scrolling so all the info was easily presentable. I just love that so much. Anyways that's my 2 cents.
