How is RSS not included in the blogging feature out of the box? Oy!

Is there a date for this

feature?

Really? So if I have a HL Blog I can set up a RSS newsletter

is this a URL Feed that will be avaiable for RSS

Can someone flesh this out for me?

Does this mean we can input any RSS feed (externally also) and it can auto-email out to a subscriber list whenever a blog post is created?
