The two and three column templates are great for displaying
lots of posts that all have similar content. When using these
templates, make sure that the titles, subtitles, and teasers of
each post are similar lengths. Consistent use of images or videos
is also important for these templates.
The “Post” post type is the default post type on your site. The
majority of your content will most likely use the “Post” post
type. Use this post type unless your content fits into a more
specific category that fits in with another type.
