There are two ways to handle blogs.
One way is to set up a category on your site called Blogs, and then setup subcategories for each individual blogger. Once these categories are set up, you can edit the navigation menus to add these new categories. This gives your readers an easy way to find all blog content by a specific blogger, and this approach also allows you to keep your readers on your site.
The other way is to use the Grid Story Template. Many sites use this method, especially for 'Humans Of' style blogs or stories.
