My friend Joshua suggested two months ago that I make my blog page 950 pixels wide (up from 800 pixels).
I finally waded into the css sheet and did it. So now the center column is 550 pixels and the sidebars are the same width.
If anyone has a problem reading the blog now that it's wider, please let me know.
I like it better because I can get more content above the fold and it emphasizes the center column more.
