It’s nice trick from Steve Mann.
In SharePoint to create new blog site we have to create a site in site or site
collection using blog template. Instead of adding new blog site, we can add the
blog to existing site by using a simple command in SharePoint 2013 by enabling
blog content feature.
To add a blog to existing site, open SharePoint management
shell and enter following command below,
Enable-SPFeature -identity "BlogContent" -url <Site
URL>
Here Site URL is URL of the site.
After activating the “Blog Content” feature we can see the
blog related items in the SharePoint site. We can check the webparts with blog
related content as shown in the image below.
