It's somewhat amusing to see these surveys and articles by people who don't really understand the Gatekeeper system that Facebook uses for deployment and the vast amounts of data they collect about user behaviour. Facebook can do test rollouts of features to specific segments of their users and exactly measure the impact. In comparison, making a survey gives you crap data that tells you nothing about how the usage patterns of Facebook will change. Because what people say they will do and what they actually do are two different things, and Facebook keeps very quiet about the actual patterns. Sometimes though you can infer that announced features actually wasn't a success. They'll just be quietly rolled back or changed or never rolled out to the entire userbase. What happened to Timeline, for example?
