Just a few thoughts:
Control or share?
In this discussion, sharing is talked about as collaboration. Sharing is giving out ideas and content but also getting, or being exposed to, ideas and content. If you view online networks as an open, lateral systems in contrast to the controlled, hierarchical system of formal ed institutions, then in moving to sharing ideas/content online you relinquish control of those ideas. You also give up control of how people interpret or use your ideas. However, your participation exposes you to multiple, diverse views – key to growing your own learning and expanding your ideas. Collaboration also connects you to a wider engagement in (the common goal of collaboration). I believe it's the giving up of control that is uncomfortable for many.
Alice asked, “Can we tailor how others see us?”. Cindy suggests awareness of what online participation means in terms of searches and data mining will result in people controlling their online identities – as we control our F2F identities as appropriate to our participation, e.g.at a staff meeting, out with friends.
I've noted, and found it odd, that a person who may control sharing of content online in a professional mode, may share freely in a social network ( perhaps resulting in being kicked off an electoral slate as we've seen in Vancouver). Yet those modes of online participation are not separate, as many reported in the first activity.
