Value in virtual worlds comes through virtual practices that assign meaning and value to particular objects in-world through virtual artefact exchange both in-world and outside the virtual world (whether in MMORPGs or SL) – so when companies wish to establish “virtual markets” with products from our everyday life outside of the virtual worlds – what are they expecting?

Similarly, when we teach in SL and try to reproduce the four walls and powerpoint in-world and then state that that does not work – what are we expecting?
