Building an audience for a blog is important to enrich content, attract sponsors, and sustain blogging over the long run towards ultimate goals. The key is to write frequently, plan ahead with idea lists, and post a variety of content like stories, questions, slideshows and videos. Interact with commenters, conduct polls to engage readers, and network by reading and commenting on other blogs to build connections. Use "sticky" techniques to keep readers engaged like related posts and newsletters. The right audience size is interactive fans, not millions of casual viewers.
