Still not sure where Twinity is going. It may have stopped developing for a while. Bringing back the streets may not just depend on affording the map data. I guess hosting the data has a cost also. So I am trying to think of other ways of relating to real space.

Any sort of conference or meeting such as #mtw3 or #mosocoop can benefit from online presence in various forms.
