The old theme is back—temporarily. Why? Nobody liked the new one. Or they only liked it conditionally. Or they loathed it.
The overriding theme of the complaints where that the new format was difficult to read, particularly single posts. And since the words are the main point, and not prettiness, I had to agree, much as it breaks—though, perhaps dents is a better word—my heart.
Your wish is my command, so I have temporarily restored the old theme until I can find some way of undullifying this one, or I find a new one.
But other—more exciting!—changes are on there way soon. Hint: stay tuned.
Update: This theme, which as you can see has been modified, is staying. Thanks to everybody for the tips.
