AFAIK every successful IM platform out there is successful because of this effect. Users push their peers to adopt the new IM because without their friends it's not very useful to them.

Of course there should be a good reason for the "seed" users to get on the new platform in the first place.

even with PRISM and others, people are too lazy for that.
