For me content is most important for making a blog worth my time, but it is being customized that make a blog great. There are so many themes availible, but I view them as a template for whatever you want to create with it. All of the banners, backgrounds, sidebars, etc. can be customized as you see fit, providing you with an infinite number of possibilities. Blogs that take advantage of all that really catch my eye, and those that don’t I usually forget. So if you haven’t done anything to make the theme you chose your own, I highly recommend going to the dashboard and getting on it. Just remember, customizing your blog is needed for greatness but post quality is needed for it to be good.
