The late Nora Ephron writing on HuffPost in 2006 explained that:

getting heard outside the world of blogs occasionally requires that you have something to say. And one of the most delicious things about the profoundly parasitical world of blogs is that you don’t have to have anything much to say. Or you just have to have a little tiny thing to say. You just might want to say hello. I’m here. And by the way. On the other hand. Nevertheless. Did you see this? Whatever. A blog is sort of like an exhale. What you hope is that whatever you’re saying is true for about as long as you’re saying it. Even if it’s not much.

Among her many accomplishments, Ephron wrote the script for the lovely romantic comedy When Harry Met Sally. She died in 2012.
