Jeremiah breaks down the future of the social web into five eras:

1) Era of Social Relationships: People connect to others and share
2) Era of Social Functionality: Social networks become like operating system
3) Era of Social Colonization: Every experience can now be social
4) Era of Social Context: Personalized and accurate content
5) Era of Social Commerce: Communities define future products and services

He talks about what’s happening or will likely happen in each of these eras. This is a great way of thinking about the social web and is a great guide for anyone looking at this space. Here’s a clip of his presentation where he previews the five eras.
