What does it mean to "follow" another user on Fluther?

I have “followed” three people, and five are following me, but I cannot find what this actually does in practical terms. Is there a page somewhere showing the activity of people I’m following?** Should I get notified when they answer questions? Or is it solely to make a list on my profile?

** If this doesn’t exist yet, I think it should. I’d love to be able to see, all in one place, a list of links to answers made by people I follow.
