I am fully aware of the importance of propagating the blogs' RSS feeds into as many feed directories as possible.
These feed directories further feed major RSS feed readers like Feed Demon-a product of News Gator. It is a known fact that the feed readers are widely used by thousands of web masters. Even I too use feed demon and have subscribed to hundreds of RSS feeds in various niches that my blogs are built upon.
Indeed, I am sad that my blogs' feeds are not returned by the News Gator searches for feeds.
Submitting to the feed directories is a cumbersome process and very monotonous. Here is a tool that would wash all the dirty linen for you.
