One other RSS feed directory to get into is http://www.feedage.com, this will spread the content of your site to a wider audience. The current amount of feeds on there is close to 6 million!
So go there, create a free account and how get your RSS feed onto to feedage by using the submit option.
For WordPress users you can add the URL http://www.feedage.com/submit.php to the Update Services in the Settings > Writing as explained in this RSS ping post. Or you can also add a plugin called Feedage Tracker which will submit your sites RSS feed to Feedage, but you still have to have an account set up on the Feedage site which is free.
One final note is that if you still want to channel your subscribers through Google’s Feedburner as described here, when entering the feed address use the Feedburner format address; for example this sites’ Feedburner address is http://feeds.feedburner.com/seo-hub - whereas the regular RSS feed address takes the format of…http://www.seo-hub.net/feed/
