I have noticed that there does still seem to be some Confusion amongst Residents as to precisely the relationships between Linden Laboratorye, the Grid itself, other Parts and also the Broader Aethernet, which does seem to be causing Misapprehensions as to the origins and behaviour of certain Aspects and Components.
I am always of a bent to properly Explain the Technical Nature of how these things operate, and for that purpose I have prepared a small diagram of the Cosmology of the Grid and Second Life, which I hope will prove useful. No doubt other Grid-Cosmological Types will have disagreements with the Details, but I believe that the basic structure is sound. Please excuse the poor handwriting.
(Let it not be said, of course, that this is more than a Descriptive Diagram, by no means Normative - we have been placed in our Spheres, and perhaps this is not Just or Fair.)
