This is a project of mine I have just started a couple of weeks ago, it has received a good traffic and we have a few things that will help you get more hits. For example if you use BOOSTER, your website will be in the front of all our pages for 30 minutes, you can receive a lot of visits in that ammount of time, of course this will come in handy when the site will be big. Currently 75 websites are in our directory and the Alexa rank is getting better and better by every update. This directory transfers pagerank, but since the website is new the pagerank is 0, help it get bigger to help you. The website is on .org because the other extensions were taken and because this is a non-profit website, as you can see no stupid ads are displayed on my directory.

To be honest with you, you have an eye-catching design but it looks like a blog more than a directory.
