By Michal Regunberg, SM& Senior Vice President The Boston Globe’s David Filipov, whose father Al was on the first plane to hit the World Trade Center on 9/11, wrote a moving and riveting story about that day and the 12 years since in a way that I have never seen before: through a series of 22 Tweets. (@davidfilipov). Like a gripping novel where you are turning each page to keep up with the action, these Tweets had the same effect: you waited for the next…and the next. In this case, you really had no way of knowing how many tweets there would be, and it was very possible to miss some of them. But it didn’t matter because each one of the Tweets, with its 140 characters, told its own story. It’s not unlike when you start a good book but don’t end up finishing it: you get a snapshot or you get the whole story. His Tweets had the same effect. There’s a liberating feeling about what Filipov did. So often the 140 characters seem to restrict how much you feel you can say. Instead, Filipov demonstrated there’s a way to use the technology to expand (not contract) the message, and to tell the story he really wanted to tell.
