Thesis and Genesis are both great frameworks to use to build your next WordPress site. They are not that hard to learn either. You can also download extensions and child themes to speed up the development process. If you are looking for a modern business theme based on either of these frameworks, you should give Junction a look. Junction is compatible with Thesis 2.1.x and Genesis 2.0+.
Junction has a responsive and very clean design. The front page has featured widget areas, so you can display the information important to your audience quickly. You can add custom post headers, maintain a side-blog, and showcase corporate or personal photos. Junction is ready for Retina displays and HTML5 optimized. A landing page template is also available for you to use to push your services.
Junction is designed by the folks at Themedy. Just like a few other themes of theirs we have tested, Junction was quite easy to install and get to work. Just make sure you are running the right version of Genesis or Thesis.
