The layout is very nice and it's obvious that Filburt has put untold hours into tweaking it... but the postbit design screws with my eyes.
I find myself having to focus on each post to determine where the boundaries exist between each one. I think it would help if the postbit table's background was a shade or two darker than the background of the site itself, that way the eye would be able to more easily detect the start and end of each post.
Just my thoughts. Otherwise, **** good looking site!
