HSX.com already ran the beta redesign over a year ago and it was AWFUL. I nearly quit the last time. It's a very pretty color scheme, but the tables are hard to follow with your eyes. Dropdown menus are overused. I know with the old beta there was some experimentation with some market survey features or some weird social networking nonsense, but this website isn't designed to create a social network a la myspace or facebook. (and I'm sure you know that myspace is laying off 40% of its staff.)
Please post your feedback to bring the old site back!
