I just downloaded the free version of RSS Submit which only allows you to submit to 10 rss directories. There is a list of other rss directories it will submit to with the paid version. I checked through them one by one and realized that the majority of them are dead links, paid directories or not even directories at all, or the domain is for sale. I have no idea how people are using rss submit automatic function. How could it possibly work?
