It is possible you know, being too lazy to be a successful blogger. It happens to many people, the reality of managing a blog is very overwhelming and can weigh negatively on the blog owner. This creates less interest in actually blogging online and fully running the site. Sometimes you won't post as much, or you won't research an article as hard as you normally do. In the end the side affects of being a lazy blogger is a slow or no growth blog. Being the owner of a large social network I've seen this type of blog decay happen very often.
