invite only social network (Score: 1) by billshooterofbul@pipedot.org on 2014-07-02 17:13 (#2AN) If google had just made it open to anyone, it would have turned into facebook. But, they left it invite only while myspace and later facebook were open to the world. Invite only services only work for open systems ( read email) or for services without competitors. Orkut wasn't open and had plenty of competition.
