Link detail pages help a directory grow exponentially on every submitted entry. However, it is a catch 22 because the same entry has already been submitted to every other directory before yours and will likely end up being indexed into the supplemental index. This is how I feel when making the same entry submission to thousands of different web directories to get a backlink. One site in particular having success with this approach is AboutUs.org that lists your submitted site in a wiki format and comes up top ten when you search by your submitted domain name. Their natural search position is better than KellySearch, in addition to the flexibility of editing your entries in real time wiki style.
