Four years ago, Twitter was headed in a very different direction (and was under different leadership, too). So I'm not sure that it would have been correct to predict that Twitter, as of four years ago, would end up as it is today, since much of that is due to things that happened in the interim. That said, the writing has been on the wall for quite some time, even if not quite four years. I remember thinking that something like this was inevitable last year (circa July 2011), and I wasn't even a developer on Twitter's platform, so there were probably signs much earlier than that too.
