Diversify and develop the types of posts you write for your blog.
Consistency is good, but variety holds your readers' attention and brings repeat visits. Seek out new perspectives on old topics. Keep yourself in the know about what new blogging software developments can help you improve the look and offerings of your blog. Try giving the occasional survey to see what your readers think about current events or your topic. Try adding audio or video. If you don't know how, learn. Have fun!
