Like many of us I guess, I am disillusioned that the rich promise of social networks for informal learning and the sharing of knowledge has been overwhelmed by endless drive for monetization. Even such basic features as privacy and data security seem to be determined more by how to make money than by any ethical concerns.

I long ago lost faith in Facebook. However, I still have a soft spot for Twitter. Even though curating follower lists takes some time, it is amply paid back by the links to so many things - reports, papers, blogs etc.I would never have stumbled on before.

All this is a rather lengthy prelude to two slides I found last week. Sadly I have lost who was the creator (anyone care to claim them?). But these are great slides.
