Created README.md

This is generally a good practice for projects on Github. It basically says what your project is and displays on the repository page.
Added Header Information

Added information to the author and description meta tags. These tags are used by search engines such as Google to basically quickly describe your website and say who made it.
Fixing the <a> tags in the header.

Previously, lots of things were not clickable because the <a> tags were not properly wrapping text.
Adding nested media object.

Your current method of having comments on a post works fine, but this method also works fine, and doesn't require you to use <ul> tags to get the proper positioning.

As a side-note, when using a <ul> child, the children should always be <li>s, not <div>s. This issue is related to something called Semantic Markup, which basically just says that you should use HTML tags as they are intended (<ul>/<ol> for lists, <table> for tables, <p> for blocks of text, <h1> for page headings, <div> for anything), because things will act more uniformly across browsers and your HTML becomes descriptive of the actual content it is representing.
