Blackhat link directory. PR4

I have a pr4 link directory that is blank and I need to find some directories that aren't the everyday run of the mill directory to get some ideas of what kind of categories to add.

I'd like to stay away from the general type directories and lean more towards webmaster resources, etc. For instance have main categories such as whitehat, greyhat, blackhat and also things such as blogging, scripting, forums, web design, etc.

This is my first directory and I'm kind of lost. How do you decide which categories to add? I know I can add a category dump but I have yet to find a decent one.

here is my Directory

its still growing. I have not done much with it. Looking at selling it if someone makes a good offer. lol

I may have to think of my own categories. I have yet to see a directory like I have in mind
