As I said in my intro, I'm about to start a directory of my own and this is one of the biggest fears that haunts me. I'm not sure if directories will still be used as much in the coming years and if they will still maintain their popularity as in the yesteryears. We all know that anything that enjoys great popularity online eventually comes to a screeching halt sometime. So will directories still maintain their popularity/usefulness? More importantly, will companies still be willing to pay to be on them?
