I have had very interesting discussions about this topic lately and you (and Jacob) are right that to change an organization culture in to more social and collaborative, it needs leadership support to make this happen. Whether an organization should appoint a collaboration officer depends a lot in what stage that organization is. It may be more effective to distribute leadership to people across the organization in stead of making one person responsible. I am planning to write a blog post about this soon so stay tuned..
