An article can be quite long without a conclusion, but since this is a blog post and not an article, I will offer one here.
Do you need a sidebar on your blog?
There are pros and cons to having a sidebar on your blog. The pro is that it can add extra content and make your blog more visually appealing.
The con is that it can take up more space on the page, and some people find sidebars to be cluttered and distracting.
Ultimately, the decision of whether or not to add a sidebar to your blog depends on what you think will look best on your site and how much space you have available. If you’re unsure, start with a minimalistic sidebar and see how people react to it before deciding to add more content or take away content to make room for a sidebar.
