FeedPing Offers Free RSS Submission to All Major Directories.

Pinging a feed isn't the same as pinging a blog. Pinging a feed simply submits the feed to all the feed directories so that it will begin to track the syndication.

Submitting to the directories will allow people to find your feed easier and thus increase subscribers and traffic to your site.

Other ping sites are for blogs, not feeds. They are meant to update blog directories with your latest entries. This site is meant to submit your feed once to all the feed directory sites and have them track your updates automatically.
