There I commented as follows:
Typologies probably do more harm than good, but I love them anyway for the order they bring to our universe - even if we only pretend for a little while. But I also believe it does progress the debate, especially in emerging sciences...
The true entrepreneur: creates and sells solutions. Pioneers of the web as channel.
Intellectuals: observe, analyse and shape the debate. Pioneers of web as medium.
Aggregators: Harnesses the content and shapes the flow without creating anything new. Pioneers of web as real estate.
Enablers: The oil the wheels of the net. The 'eyeballs' everybody is chasing. Comment but don't necessarily create from scratch.
And finally, any combination of the above.
PS: Don't know why I called then 'participators rather than participants, but it just sounds less passive in recognition of the vital role they play.
