One concern for bloggers is PR rank. I think this is gained when there are more traffic for your site. In order to get higher PR, you must join some blog directories where you can gain exposure for your blog. Recently, I found one site which truly helped me. I joined Buzzfuse.com and from the day that I became a member, I noticed that there are a number of individuals visiting my site. It has helped me build my traffic a lot. I just had to upload the picture of my blog and everything else follows. Why don't you try it too... the more post that you send to the directory, more visitors will be interested on your site.
