A few months ago I read the book "Leadership and Self-Deception". Then I became a friend of the Arbinger Institute, went through some training with them in London and may be involved with them in the future. So I suppose the book inspired me – here’s why! Guest book review by Mario Gastaldi.

Any social organisation from the smallest team to the largest enterprise carries with it a social network. Until recently these social networks were largely invisible to the organisations which depended on them. Now Social Network Analysis or SNA is a hot topic but what is it, where did it come from and how does it work: Richard Cross, bioteams.com Guest Author, explains.

Way back in the social networking Dark Ages, OK - October 2005, I published a "A Virtual Community Development Model" with sports metaphors for each stage. Looking back today I think some of it still applies to the development of those social networks driven primarily by shared interests/knowledge (rather than by relationship building). But see what you think?

These days lots of businesses are trying to use social media to enhance their online presence. Unfortunately only a minority are really succeeding. Many of these are businesses that are highly digital or naturally global. However many businesses do not fit this model and are working in local markets with non-digital services/products. Can "normal enterprises" exploit social media too or does it only really benefit the global digital elite?
