Now, I was actually impressed by the way they decided to take the whole "viral tell a friend" thing; (still being operated via email scripts); and updated it via the two top social sites. kudos to them!
Cool idea, actually; (started through Twitter's "tweet this" functionality). Basically, after the opt-in.. "Tweet/Facebook this and we'll give you this free gift"
Thing is, they kinda jumped the gun with Facebook.
Yeah, its cool that you can integrate Facebook with your various web pages/sites... pretty seamlessly, actually, (cool stuff)... BUT.. because FB users are more savvy these days, FB implemented all their privacy tid-bits.
Now, I'm not going to sit here and post how to get around someone's marketing; that would just be shi%%y of me and I'm not that kinda guy.
But TRUST, you can not use Facebook like you do Twitter's "tweet this" function and hope to get accurate data and/or solid push marketing because of those privacy tid-bits.
Now, since these guys are some of the biggest on the net.. I'm sure they're figuring "What the hell. What % of the people going through this funnel will know how to defeat this? Dismal to us."... which could very well be true to some extent FOR THEM... remember, they're the big boys.
Yet, for those that do NOT have access to a multi-million member list factory and the ability to blanket the entire IM market with their campaigns... it would behoove you to walk carefully down this road; as that dismal % could be much larger for you.
I will say this... it is much more advantageous for you to use FB's commenting system on the front end and save the deeper more "friend viral" stuff for later in the relationship; once there's one established.
People are very protective of their friends.
