Wow! One can sure see two different points of views on the purpose of a directory in this thread... There are those who look at it in the vein of building a quality directory that lists relevant resources. Then on the other side there are those who say well google ain't paying me so people can find google on their own... LMAO. Anyway I don't see how listing ones own directory in the relevant category causes any harm. Honestly my thoughts are that a visitor would expect to see it there.
