If nobody beats me to it, maybe I can look into making an Amazon API plugin for WordPress after I finish adding MetaWeblog and MovableType API support to the xmlrpc interface.
The Technorati API will be fun to play with, too.
Hmmm…. This might be a good addition to the documentation as we work on it. “CSS Tips & Tricks”. We could come up with some “cookbook” CSS recipes — “If you want archive links to look like this, add this rule….”, etc.
You’ll probably need some other files from CVS, as well. Try updating your copy of b2-include/b2functions.php and see if that fixes it.
Did you also launch the wp-admin/upgrade-070-to-071.php upgrade utility?
