Along with WordPress 4.4, a new default theme came as "Twenty Sixteen". With a modern blog layout and multiple widget, it is a perfect blogging theme for starters. One can also create a nice landing page using extended image and block-quote feature.
Japanese web designer Takashi Irie has designed Twenty Sixteen WordPress theme and the first version came in August 2015. Now in December 2015, the recent release i.e. WordPress 4.4 is pre-loaded with Twenty Sixteen theme. The default WordPress themes are not the best ones but has all the recent APIs or standards that the theme developers should follow.
Well, design wise the new default themes is really good. Features such as images extending out of the content area and responsiveness, is just amazing. Sites designed with Twenty Sixteen looks great on all devices.
