Theme Review
Themes that remove the wp_head() call are outright broken, as are themes that do not provide some way of addressing each post via DOM whether it’s on the H3 or the DIV. I would prefer the DIV, but then we’d be changing the way it’s done from the Default theme.
Someone needs to provide a serious review service for themes so that these things aren’t overlooked. I think there is a sad disparity between designers and developers in this arena. Designers are often very concerned about what the site looks like and whether it renders properly in every browser, but often overlook or aren’t aware of hooks that developers are using to implement plugins or other features.
