I have just upgraded the wordpress software to version 3. It all seemed to work fine. However I noticed errors in the archive pages. Therefore I wanted to upgrade to the latest and greatest atahualpa theme that I use for my blog. I should not promote it to much, or else everybody else starts using it :-).
To my opinion, the blog looks even better. The twitter items look better than before as well as the authors with the amount of blog items.
If you spot problems, please let me know.
