As mentioned by txwooley, it is a bit too busy. What bothers me most is the break between news items for showing job ads and forum posts. I visit mostly for the news and I think it is the same for most visitors. It would look less cluttered if you put jobs and forum posts on the sidebar in place of duplicate lists of news items. I think tags cloud and site search are more efficient for people to look for past posts on certain subjects. Hope that helps. I visit daily, so this site is pretty important to me. Thank you for your hard work, gcaptain.
Oh, one more thing. The newsletter signup. People generally hate pop ups, ok?:o
