I standardize some special classes across my themes. Classes used for aligning images (or other elements) or styling text (think all caps). And then there are the classes to indicate XFN relationships. Maybe we can make our lives better.
A new function, language_attributes(), is introduced in the upcoming release of WordPress. And a nice guy like me just wants to update his themes so they will work for everyone. Not always possible, but let’s consider ways to keep things forward- and backward-compatible.
New project homes on Google Code for my themes (including Sandbox) means Subversion access for everyone concerned. Also, expect better Microformats support (i.e., hAtom and hCard) in the upcoming updates to my themes (yes, including Sandbox).
