The control over the YSM Ambassador program has been shifted over to Kowabunga, since late last year. A thread at SEW Forums asks why is this?
As Moderator JohnW puts it:
I guess the real question is why Yahoo would outsource something so important to their business. The affiliate side of it, I get. The Ambassador part, I don't get.
Not many replies to this thread yet, but an interesting topic of discussion. If you ask me, I would say Yahoo is outsourcing this in order to dump the affiliate workload mostly, but also to not "have to deal with" smaller SEM's that may not have even reached Gold status yet for any of their clients. But I'm cynical like that.
