Are operators going to get this, some day?
“So, why do Web 2.0 services work? Because they mirror the user’s social graph and focus on user generated content (UGC is a form of communication). In contrast, the mobile services do not in most cases. All your friends are not on the same Operator – you don’t live your life like that! Since mobile services are not interoperable(excluding voice and SMS) – they do not reflect the social graph.” – ajit @ Open Gardens
(But the same really applies to online communities – hence the need for inter-operability between all the facebooks of the world. I am more and more pained every time I ponder asking my friends to confirm me as their friend, again, when I sign up for yet another service.)
