What is this all about in WordPress.com with the different kinds of format for posts?
This is what the WP support page says about the formats:
Standard – Your normal, average, everyday blog post. This is the default styling for your theme.
Gallery – Usually will show a thumbnail from the blog post, as well as an excerpt of what the gallery is about.
Aside – These are brief snippets of text that aren’t quite whole blog posts. Useful for quick thoughts and anecdote
I am going to mark this post as an ‘Aside’ and let’s see what it looks like.
Having seen the post I now see that the whole of the post is laid within a yellow box. Oh well.
