Community, collaboration and content
That's what Adam Bosworth says the platform of this decade is about. And he's right on. The portion of my day that I spend using Web tools is typically much greater than the portion of my day that I spend using thick/rich/smart/whatever-they-are-calling-them-today clients. As some commenters on Adam's post pointed out, you still are going to have private content. But does that mean that you won't have a web interface of some type. Clay Shirky's concerns are valid, but I believe that they can be addressed.
