Couldn't your Point #1 also be said of MySpace before?
The problem for Facebook is that the cost for the users of switching to a newer social network site is practically zero. A little bit of time to create your profile, but no real significant costs.
If 3 of your most significant friends from FB emailed you about a new, free, social site, would you ignore their emails, or would you go check it out and maybe join them? If you joined them, how many people would YOU attempt to drag over?
but Myspace never had the effect of Facebook because the social aspects are limited. The tie-in is not as string as Facebook and how many of us actually had a myspace page we updated regularly when Myspace was big? The privacy aspect of Facebook has prob been the main difference between the two companies
Social aspects aren't especially more limited in Myspace. You have friend lists, bulletins, status feeds, and profile comments-- all of the most popular features of Facebook. You don't have "MySpace Apps" but people add stuff like quizzes to their pages and send questionnaire bulletins all the time.
