BT's social media evangelist JP Rangaswami puts forward a typically plain english perspective on how business communications could fundamentally change, were enterprises not to ban Facebook. Have a read.
I'm wondering whether internal comms bosses at places like Lloyds TSB, DrKW, British Gas and those other places that are banning Facebook are fighting hard enough against the IT managers that have made these decisions.
JP used to work at DrKW. He also remembers when direct phone lines and internet email emerged in the enterprise and were also banned, for fear they would hamper productivity. So he knows a bit about what's going on. Every enterprise has a choice, he says, to catch the next boat home, or to send for reinforcements.
