Very informative. I like it.

I would like to suggest a website directory that is intel based called QASSIA. Intel in this case refers to intelligence and translates to articles. You've got very good original articles, i must say.
Qassia is an auto-cascading website directory, powered by a credit-driven knowledge repository. With Qassia,you can add your websites for free, and without having to add reciprocal backlinks. You’ll get unlimited quality backlinks. You get one backlink for every piece of intel you add. Every intel will carry a direct backlink to one of your sites. So the more intel you add, the more backlinks you get.

Qassia is slated to be one of the best ad revenue sharing system on the Internet, so in effect you get paid for promoting your websites.

Unfortunately, if u got to Qassia main page, it will tell u that its still in its beta stages. So signups are by invitations only.
But should you like wat you see, may I extend my invitation to you via this URL ad8cents.qassia.com

So give Qassia a spin, you've got nothing to lose.
