Blogs in a Nutshell

What is a Blog?

A blog is short for web log and is a collection of posts (articles) containing reports, media (photos, videos and pdfs), links, etc. shared with others online. Frequently it’s a type of website or (as in our case) part of a website.

Our blog is mainly for group leaders to share reports and photos of their activities and to showcase some of their group’s work. Some groups also use the blog for supplementary material for their group meetings.

What is the difference between a Category and a Tag?

The list of categories is like the table of contents in a book and the tags the blook’s index.


A blog category relates to a particular topic. Posts related to that topic will be found within it.

Using categories, we can organise our posts to group them by related topic or theme. In our case, the category is usually related to a specific U3A group and managed by the leader of that group. Registered users can subscribe to the categories they are interested in (for example, the groups they belong to).


A tag is another way of classifying a blog post. It is a word or set of words (keywords or keyword phrases) that help define what a post is about. For example, this post may contain the following the tags: blogging terms, blogging glossary, blog terminology, blogging descriptions, and so on.


A post is an article within a blog and it can be on any topic.  It’s the collection of posts that form the basis of a blog. To help our users find what they are interested in, we try to assign a post to a category and to add the relevant tags.

What is the difference between a Blogger and an Author?

The person who writes for a blog is referred to as a blogger and the act of writing for the blog is known as blogging.

The Author is the name of the person who wrote a blog post. This is usually a Group Leader.

What is an Avatar?

This is a photo, graphic or image that identifies contributers across blogs and social-networking sites. This is not required nor used by all, and is sometimes displayed within the profile or comment sections.

What are Archives?

They are a collection of previous blog posts that are no longer shown in the main lists.
