Presence will increase Minutes

Alec Saunders blogs about iotum and its new Talk-Now service for Blackberries. Talk-Now is a Presence app. Alec explains Voice 2.0:

Today, callers have no way of knowing whether the party being called is available, or busy, or would consider the call an intrusion. We can all relate to the problem Talk-Now solves on an emotional level — it lets us know when the people we need to speak with are available, so we don't have to play telephone tag.
