As Jeff has pointed out (to some controversy), when a new blog post is made the blog link temporarily replaces the chat link in the top navigation bar. He also points out (with a copious amount of arrows) here, that most SE sited have a chat box thingy on the right hand side. Unfortunately, Server Fault does not have this chat box on the right hand side.
From top to bottom, I see the "Do you haz teh codez" ad, the Careers 2.0 ad, the tag cloud, and the recently awarded badges. If you're going to remove the link from the top, can you please make sure that the side bar thingamabobber is working?
