I'm guessing he means making every other post/thread a slightly different shade, for contrast? I was hoping that the big spaces made it readable, but there might be a way to change it via theme.
If you want, Khahan, feel free to make a post about this in the "Feature Requests" thread, so people can vote on it, so I know if it's an issue for other people, too!
I have one small gripe. The username and picture at the top of each post, not at the side as in a traditional forum. The conversation doesn't flow as much in this format as it does in a traditional forum where the text of posts follows one after the other after the other. Also maybe I'm just a grump, but I like the traditional forum styling better than this new bubbly pastel colored look.
