Submitting your pheeds to all the directories is essential and is an important Bomber strategy.
Again, you want to think of RSS pheeds like you would blogs, sites, etc, in that you want to create as many of them as you can.
Every time you create a resource that exports RSS, you MUST:
1. Submit it to all the directories (and ping)
2. Add it to your main BlogBomb that contains all your RS pheeds. (This should also be submitted).
3. Once you have enough pheeds, you can use your BlogBomb feed to not only cross-link, but also to generate content for tin sites that accept RSS.
