On this week’s ITConversations show I asked Martin Murray, who is chief spokesperson for Public Service of New Hampshire — and @psnh on Twitter — to tell the story behind this atypical pattern of Twitter followers:

The quantum jump occurs on December 13, and corresponds to the epic ice storm on December 11/12. The storm temporarily knocked the majority of New Hampshire’s homes and businesses off the power grid, and for many the outage lasted days or even weeks.

When I visited the Public Service of New Hampshire website to check on the status, I was delighted to find Martin’s Twitter feed. Gary Lerude had anticipated my question:

@psnh How about an online map showing the areas without power? We could see the progress of the crews as the power is restored.

Three minutes later Martin replied:

@garylerude Good idea – working on it!

I thanked @psnh for the response, and for the company’s ongoing restoration efforts, and added:

@psnh Incidentally if you need help publishing your data online and creating maps, lots of us here are good at that and happy to help.

The response:

@judell Yes, ur google map screencast of Keene walking tour comes to mind. We may follow up on ur offer!

Whoa. This is definitely not how your grandfather’s utility company handles public relations!

In this interview we discuss Martin’s use of social media in the wake of the storm. Of course he has been interviewed elsewhere and more prominently on that subject. So I also asked Martin to reflect on how business-as-usual may change going forward.

Of special interest to me is the portion of that chart beyond Dec 13. True, the follower count has plateaued. But it hasn’t plummeted, and won’t, because it costs followers nothing to stay tuned in to a quiescent channel. If PSNH uses that channel judiciously from now on, I’ll stay tuned in. If the channel annoys me, I can silence it. That’s analogous to unsubscribing from an email newsletter, but better from my perspective because the unsubscribe mechanism is obvious, uniform, immediately effective, and fully under my control.

How will PSNH use this channel for normal, non-crisis operations? Martin thinks that customer service with a human voice is the way forward, and I violently agree.

Consider this exchange:

@psnh tweets: “Explanation/options re high ‘estimated’ bills sent to some customers: http://tinyurl.com/8de4kl”

@sjudd tweets: “The real question is why are the estimated bills higher than expected? Will you tell us later if any estimate was lower than actual?”

@psnh replies by direct message (quoted with permission of both parties): “I doubt any est bills were lower than expected. Computer based it on Dec 07 usage. Apologies for the error!”

That’s what customer service used to be and — let’s hope — will be again.
