This weeks Carnival of the Mobilists is at Michael Mace’s Mobile Opportunity and it’s a great one. Michael has highlighted Daniel Taylor’s piece about the recent Blackberry service outage as post of the week. Michael liked it so much he made it part of the title of his Carnival post. I agree that it is the best post of the week but hardly the only great one. I especially liked Jason Devitt’s explanation of why the prepaid MVNO business model works when highly funded MVNO’s like ESPN, Helio and Disney are having a hard time. Other posts that I struck a chord for me were the debunking of cell phone myths by Shackdiesel, and Tomi Ahonen on why business execs should text like teenagers. But that’s just me. In truth all this week’s items are good. Head on over to Carnival of the Mobilists #70: Is RIM stupid or lying? and see for yourself.
