Okay, so, this is my third web design in 4 months. Looks a bit like the original design, because I decided that I liked the original palatte better. I find that I'm not very good a picking out colors! This time, though, I think the darker background makes the site less monochromatic than the original.
The only thing I really changed this time around was the style sheet, plus restructuring the home page a little bit. Feedback on the last design indicated that it was more desirable to see the latest entry in full on the home page rather than having to follow a link to it, which I think is reasonable for a blog. All the adaptive and other layout elements of the most recent design have been preserved, so, on the whole, it was a pretty minor change.
