I've been thinking about why I don't like the new forum, visit less, and am less likely to post.
The problem is not with the people here, so that is at least something

No the problem lies in that everything is so glossy and smooth. By that I mean that when I look at a forum, or the forums start page for that matter, I can't at an instant see where I want to go. Everything is slick, smooth, and so hard to distinguish from each other, that my eyes just slip past what could be interesting forum posts or interesting forums.
This lack of distinctiveness is really a problem. I see more posts in the wrong place than ever before. This is just one indicator.
I feel I've given the new forum a good chance now, and I can say, that I don't really like it. I wish someone would do something about it, but they probably won't. What is your feeling about the forum? Does it work for you? And why/why not?
