This plugin is intended to improve the usability of WordPress’s built-in Post Formats feature exclusively through some 
key changes in design.
The unhelpful list of radio buttons is replaced with with Retina-compatible icons, format titles, and brief, helpful 
descriptions of each format. Instead of dramatically changing the way WordPress works, Better Formats simply tries to 
make the existing WordPress Post Formats feature more friendly and informative.
Additional user-centric improvements are planned. This initial release is intended to help spur conversation about Post 
Format improvements currently being considered for WordPress core.

Go to the homepage or blog page of a site, chances are, all of the posts look similar: A title, an excerpt and a featured image. Why not display the most important part of your posts to readers and actually give them a reason to click on your post a read it? That’s what this plugin does.
To enable Post Style formatting functionality, go to Settings->Reading and select “Enable Post Style formatting.”
McNinja Post Styles is what we always wanted Post Formats to be: powerful, flexible and extendable. Unleash the creativity of your content.
McNinja Post Styles can display content based on the Post Style of a post. For example, if your post has a video in it and you’ve selected the ‘Video’ style, your blog page, category pages, etc. will display that video rather than an excerpt.
Post Styles can be selected for a Post from the ‘Edit Post’ screen.

It's like Post Formats, but actually useful. Every post is unique, start treating them that way.
