We are using Twenty-fifteen at www.PagePipe.com.

Since our specialty is WordPress UX, we wanted to show how the theme could be customized for branding and speed.

We are using the free child theme: Kiyomizu WordPress theme. It has a responsive 2-column post list. Plus if you look at our Colophon page you'll see the 31 plugins we used.

And the site loads in about 1.5 seconds on shared Linux economy hosting.

Thanks for letting us showoff!

We love your articles.
