Is this text flirting for awkward people who can't come up with their own responses or is there another use case? I liked @spartango's idea of an email version for team interactions with sensitive partners/clients/contracts... but I can't see why anyone with even average social skills would use this. I'm not sure text messaging (where each message is relatively low-value and usually to friends who don't care) is the most effective media/platform for a service like this. Anyone have thoughts?
If it shows extended message history I could definitely see some use in it. there have been times when I wanted to share texts I sent to one person with another.
It might also be interesting in situations where you want to introduce soon-to-be friends momentarily -- making them exchange numbers so soon might be unnecessary.
I often see people asking feedback from one another regarding how a conversation is going, what another person could have implied, etc. An app to facilitate sharing and collaboration over SMS conversations sounds like an extension of this behavior.
(Not endorsing it, but it doesn't strike me as something that only socially clueless people would use.)
