Technical Question about Rss Submission

When you create a blog (let say in this case a blogger blog) you sumbit your first post and then the rss to as many rss agreggators as possible. Does it mean that the rss directories will automaticaly syndicate the next posts on the same blog as soon as its hit the web?

Sorry if its sound newbish, but I'll appreciate any help

I was hoping it's the opposite... anyway, thanks a lot
