I think anyone that was even mildly creeped out by Secondlife or Playstation Home will be about 10x more creeped out by VR versions (not even adding in the Facebook angle).

VR "Presence" cuts both ways.

Yes it massively amplifies virtual experiences but disruption, incongruities and annoyances are amplified to the same or perhaps a greater degree...

I think it will be more mainstream and captivating and thus effective than SecondLife. For one thing, you will be invited to join existing friends rather than jump in and deal with randoms.
