Picked this up on Socialmedian:
Type 0 and 1 plus:
- Social media and Web 2.0 (social news, social bookmarking, and social networking)

- Audio and video blogging
- Open IM clients (e.g. GTalk)
- Wireless connectivity
Communication advances have generally created faster and easier to use methods. In the pre-Internet era, nothing was faster than a phone call except for a face-to-face meeting (although travel time to arrange a face-to-face meeting was often prohibitive). Today we have a number of methods that allow virtually real-time interaction and more variations on them seem to appear on a regular basis.
Lots of visuals in this post. The author seems to be alluding to attention economy variables in Part II.
