Some people (including me) appreciate a little heads up on the length of a blog post or, more importantly, how much time is it going to take to read. A great way to do this is to display an estimated reading time and/or word count at the top of your blog posts. You see this feature on popular blogs like medium.com. It doesn’t have to be intrusive or distract the user from engaging with the content. But it can add a nice UX boost for those who spend a lot of time devouring content on the web.
