User interfaces are always subject to opinion (beauty is in the eye of the beholder) but I've often found that just because something can be done, doesn't make it the best thing to do.
JQuery scripting errors are abundant on the Shoutcast.com website when viewed by the world's most popular browser, and have been for some time. AJax has its place, but not if it renders a site unusable or unfriendly.
Sometimes, if it ain't broke, don't fix it... lol
The Shoutcast team are working hard to try and provide a good experience, and I'm not knocking their efforts. But those of us in tech, armed with Firefox and Chrome, tend to forget that more than half of Internet users still run MSIE.
@Nick - Google Chrome will probably fix the broken "Show More" issue you're experiencing from time to time. There's still no slick way to show 50 results per page like there used to be though.
