Tomorrow, phone communications-oriented social networking site Ccube will announce its new click-to-call feature will be deployable to members of MySpace and Facebook. So the point is, you see a member profile, and if you and the member is subscribed to that feature, you're on.
How will you know if a member has enabled this feature? Look for the "Call me at Ccube" button.
To launch this feature, CCube offers a free, 60-minutes-a-month pricing option. $7.00 gets users 250 minutes a month, and $20.00 allows for 1,000 minutes a month.
I think there will be some takers for this service, but the real issue will be to break the IM and texting model in which so many members of this universe are tethered to.
