Reddit threads are indiscriminate. I'd expect Facebook to filter the content to intelligently include posts from people that you know and correspond with frequently. There will probably be even more activity total across the system, but you'll see messages that you have a greater chance of caring about. I suspect one of the goals of this product is to help sports fans group together, while also keeping sports-related content off the newsfeeds of non-sports-fans.
