One of the things that I love to see is how people use different ways to contribute to the WordPress community. Outside of the usual theme, plugin, and application development efforts, there are also a number of blogs, sites, and podcasts (of which I should have more information on later this month, as well).
Thanks to Apple, the iTunes store, and the Newsstand application, authors are now able to publish their own magazines to the App Store.
One of the latest contributions I’ve found in the WordPress community is WordPress Hub Magazine.
