The site is cool, but I have a few pointers. One, center this content: "Politics Internet News Business Sports Technology Entertainment People." It would look much better centered. I also think that your logo would look much better without the green background. Use gimp, found at gimp.com to edit the photo, add an alpha channel and make the background transparent. I don't know for sure if it will make the site look better, but I would experiment with it. Here is my main concern with the site, which is not your fault. Wicked(dot)com is a very large porn site. I know that your site does not contain this material, but you should be advised that your site name is similar to this site. People may come to your site thinking that it is part of the porn site, which could possibly greatly increase your traffic and be beneficial to you. Just make it clear, if you fill out site descriptions on other sites, about wickedmarks, that you describe the site as a social bookmarking website. I hope that this review helps and Good luck!
P.S. I am quite tired and it's fairly late at night, so i'll read this again in the morning and if part of it does not make sense then I will re-write it.
