Many many things about top blogs
This can work in your favor, not only can your craftsmanship boost your blog, but so can the commentary of your readership. Taking the time to submit your blog to the directory will help to make sure your blog is getting the readership it deserves. This does not mean that you can slack off and people will just come to see your brilliance, but it does make it easier for people to discover the quality time you put into your writing. A submit blog directory is all about getting that visibility for your blog and your ideas, getting it out to the people who can get the most out of it. No need to jump right in to the first submit blog directory you find though.
