I'm mostly a non-Facebook user, but if I had something to promote, I'd be there doing it. Even with the very small group of people I do communicate with once in a blue moon, I see the trend toward the type of thing BK is talking about.
Others have already said it, but: People want to be the first with BREAKING NEWS and DIRE WARNINGS. Especially the DIRE WARNINGS. Oh, how they love DIRE WARNINGS. And they have a tendency to blindly trust things they read, whether it's from known sources or not. They especially are ready to believe that The Man or The Government or The Aliens, or whoever the flavor of the week might be, are out to get them. I'm not saying anything new here, just noting that even on a very limited use of Facebook, I see the same trends. I can't even imagine what it must be like for those who practically live on Facebook.
