I also found the new design to be too visually overwhelming. It is too much information thrown at you at once. I felt lost instantly and was not able to easily adapt to it... all I wanted to see was JUST the full forum list alone so I could get to where I wanted to get to quickly... to me this central view of all the subforums in their forum groups has become a sort of table of contents to me on this site, but on the new design it is treated like an index... it took me a while but I found the link on the bottom of the right column.
I'd almost find it tolerable if the right column was the table of contents with all the forums listed, but instead it's a "top forums" list, which is sort of arbitrary... it's more information than access, since it can't be counted on to reliably provide links to the places I want to find quickly.
Well, just wanted to put some input in... I definitely prefer the older and simpler design... I very much appreciate this site and all the hard work that the creators and those who maintain put in! But a bad user
experience is a bad user experience, and that's what I got from the new layout.
