found no reason for a commercial theme by using flatbootstrap

My site is http://minderwert.de
The site is rather technical. For this the theme is wonderful easy, though having all the excellent features provided by the Bootstrap framework.
I use the theme together with the “Bootstrap 3 Shortcodes” plugin. So content and plugin development is fully “bootstrap oriented” and homogeneous.
