What if I don't have a home ?
I guess many people in SL do not own or rent a personal place... and this doen't put us a the fringe of the society.
Many newbies like me surely look for free stuff to grab in SL... and this doesn't mean we are poor. A whole part of SL organisation even seems to rely on freebies.
You can even win money (virtual dollars called Linden Dollars by the name of SL founder) just by camping (staying) in some places...
I do not have a good idea yet of what all this means compared with RL... Maybe later on ?
