Another context: Science 2.0
Here is another context that would be worth to take into consideration and which is related to the use of social media to support science.
This is what can be referred to as Science 2.0.
This is an area that is open and that has built its own social network. It other words it is not yet "colonized by Facebook". (other sector is job search).
This area can also be considered as a critical component for innovation (in Europe). It is also an area that is relatively rich in terms of models (social networks, open publishing, etc.)
I feel embarrassed to post so much.
I hope I do not introduce too much noise in this discussion.
On the other hand I believe it is important that our community produce enough material to as to inform the elaboration of a strategy.
