I'm not sure exactly what is meant by "join" here, other than that "Automattic has hired key members of the CC Search team and will sponsor their contributions." This is at first blush a good thing, as development had stalled, as evidenced by this frozen GitHub repository. But does "join" mean "acquired" here? Will the company (WordPress, or Automattic, or whoever is in charge) continue to support (or allow) the search API, or does it become an exclusive WordPress feature? And, for that matter, why can't Creative Commons support what seems to me to be one of its most important services?
