I made a few changes to the layout over the weekend. The logo has changed and is now dynamic, I've reduced the padding between some of the elements, and, most significantly, I've fixed the width of the body.
Non-nerds may not care about this, but whether web pages should have a fixed width so they look the same on all machines or a flexible width so that they can take full advantage of large monitors is one of these debates that web designers discuss endlessly. I've always been in the flexible width camp, but of late I've begun to move into the fixed width camp.
