Sorry, but people won't move away from Facebook for something else until all of their friends do.

Does that 5 friends rule still stand up? If 5 friends are using a service people will be willing to try.... at least that was an adage of the past.

I doubt 5 is enough to switch away from a social network. I think you would need at least 25% of a persons friends before that person would consider following.
