The main drawback of RSS IMHO is that it's strictly one-way publishing. You can't comment, or like, or subscribe, or share, or sponsor directly to original author. Author might posted something really exiting and seen none of the reactions happening in all kinds of RSS readers. I think it's important if we can have a universal two-way format for long, rich written texts.
