Scott Leslie tends to his ever expanding collection of PLE images, and adds another one of his own "to visualize my PLE in a way that captured not just the tools, but the uses and the trust relationships as well." It's not a bad diagram, but I would suggest that there are many more uses and relationships than those listed on the diagram. Also, I'm not sure I'm comfortable with the ever expanding 'circle of friends' concept, as seen in the full sized version of the diagram. I don't think of people as 'near' or 'far' from me - I don't think friendship is analagous to spatial relationships (cf. Tversky on similarity, which is sometimes also represented geometrically - people become linked to me by virtue of various features that we share, where particular features are more or less slaient in any given context of interaction.
