some of that reporting is sorta off and untrue. Microsoft though has been in sl since 06, i think. I remember them having an office and everything back in 07. I haven't looked recently to see if they are still there plus they were looking to make it more private.
If Microsoft buys 2L, you can expect, the sims to go from PG, Mature, and Adult, to G, Fam, and PG.Good by all the fun, as 2L would become available through XBox communities, and the threat of kids logging into a nude or sex area, and being susceptible to lawsuits from parents, would turn 2L into DisneyLand Facade.
