A routine is not necessarily a bad thing but if blogging topics have become routine for you, chances are that your audience feels the same. One way to break the routine is to put very short survey questions on your blog asking your readers what topics they would like to read more about. What are they interested in today? Surveys on your blog will identify topics of interest to your specific audience. Just remember to keep it very short. You don't want them clicking out before they are finished and most readers today move quickly from screen to screen.
