Mind out that you don't run into problems with "bidvertiser".
Overall good site, but I don't particularly favour those sites with a white background and loads of text.
I like the logo, but overall I think you need to do something to make it different from all those other link directories out there.
Always ask yourself "What makes yours different?". If you can't find anything substantial, why will anyone come to your site over any other link directory? Make it special, for instance, make a toolbar. I am not sure how you could do that, but it is a great way to keep people using your site. Also, make it more interesting to look at. Every link directory I have been to looks really primitave, with the categories at the homepage, and then links into the categories. Maybe mimick Ebay, with the categories at the side, and then in the middle have "Website of the day" and stuff. Think of interesting things to do. You seem like a good graphic designer, so get some branding images up on your site, maybe get that fat person up around the site a bit more, but in different positions, maybe with different facial expressions.
