The main goal of the recent WordPress 2.5 was to to increase usability. Unfortunately, some, particularly at WordPress.com, have initially experienced the new release as a decrease in usability.
Overall, though, I’m disappointed with the review. There is no mention of the fact that, when writing a post, we now have to page down to assign it to a category. I am far from alone in preferring the Categories box to be at the side of the Post content box, as it used to be prior to 2.5
The review itself has some barriers to usability. I shuddered at writing such as “color that is contrastful to the rest of the design, possibly a complimentary color” (should be “contrasts with the rest of the design” and “complementary,” although the second error is nowhere near as annoying as the first).
I also object to the lack of a link to any other page at the site (noscope.com). The front page consists mainly of many large images: thumbnails, with links to larger images, would have made it more user-friendly.
Perhaps some of the above is harsh. But those who preach usability should be prepared to be judged on usability. That includes WordPress, although I should add that I consider some of the judgment of 2.5 to be hasty.
