I thought the old theme was getting stale, so I’m implementing a child of another one: PixelPower from ThemeForest. This new theme incorporates HTML 5 into a responsive design that should work well on a variety of screen sizes, which strikes me as more elegant than using one theme for desktop and laptop computers, and another theme for mobile devices. So I’ll disable WPTouch after I’ve configured and customized the new theme to my satisfaction.
PixelPower also allows many different post types out of the box. I’m interested to see how they’ll work. Maybe I could bring in Google+ posts using the “aside” post type, for example.
