Daily Blog Tips is just that, great daily blog tips. I subscribe to the RSS feed to stay up to date with the blog. This text is from their About-page:

Even skilled writers get discouraged when they realize that people are not reading their stuff. Content is surely king, but great content might just get lost on the Internet if not supported by promotion, search engine optimization and the like. With that problem in mind I decided to create Daily Blog Tips, a place where you will find simple yet effective tips to improve your blog.
