Blog directories can be a great way to increase the flow of traffic to your site. It's unfortunate that submitting your blog to these directories can be very time consuming and, in some cases, futile. Some blog directories require reciprocal links and then take a long time to list you, if they list you at all.
Fortunately, there's a blog that can help us to avoid this frustration. Blog Directories Reviews is a blog that offers reviews of blog directories. This is a valuable service. I plan on using it to find out which blog directories are worth my time.
