The problem, I think, is in the question "worth". To me, it refers to a topic or idea that I would enjoy writing about, but one that others would also enjoy reading about. What's the point of writing if nobody reads any of it? I like to use Google Adwords' keyword ideas tool to find ideas that people seek out, then I pick and choose what I like. This is a great method especially if your blog is concerned with SEO and getting search engine traffic.
