Facebook has just crossed the 100-million-user plateau, and it’s more notable than when MySpace achieved the feat 2 years ago, Stan Schroeder writes on Mashable. First of all, Facebook says it counts only active users, unlike its rival. But more importantly, Facebook has a vision of how to cater to and expand its user base—and how to make money.
                                    
                                    
                                
                                
                             
                            
                            
                            
                            
                            
                                
                                
                                    
                                        Schroeder is not sure if Facebook is worth the $15 billion some say it is, but the advantages over MySpace are clear. “Which one would you rather have: A user base that has grown spontaneously, virally, and largely because of sheer novelty, or a user base which you’ve carefully groomed, which is active and using your service because they find it better than the competition?”
