(Personally getting news off Twitter isn't a reason I use it.)

If you follow a feed that basically just outputs an RSS-esque feed of titles and links, then yes, it's just an interface for RSS.

You can also follow people and/or organisations that editorialise in their tweets. For example, if you want tech news from BBC, you could get a basic RSS feed, or you could look to someone like Rory Cellan-Jones and could follow his work account (@BBCRoryCJ) which is basically just BBC stuff, but not the same info you would get from an RSS feed with some extras added in, or his personal account (@ruskin147) where you get more personal thoughts/opinions etc.

And another option, getting news from your friends - so, in theory, that can provide you with interesting content from random different sources that fit your interests, which an RSS feed won't do. So it's kinda like what a sub-reddit is to the reddit frontpage, except purely personalised on who you want to follow.
