As I mentioned in a blog post a couple of weeks ago, Twittering about the Boston Red Sox was a big part of my initiation into the microblogging world in 2007. But until yesterday, the Twitterer whose Red Sox Tweets I saw before anyone else’s, last April — @RedSoxCast — remained more or less a mystery to me.

I didn’t know if RedSoxCast was a man or woman, or where he or she lived. There were seldom — or never — any personal Tweets to give us any clues, either. It was all business with @RedSoxCast — the business of Red Sox games, that is.

And then Laura Conaway, web editor of the NPR morning show The Bryant Park Project, did a short segment on yesterday’s program about our fanatical group of Red Sox Twitterers (she reports we’re more than 400 strong!) that at long last gave us a peek under the hood of @RedSoxCast’s true identity.

He’s Jordan McKible, he grew up in New Hampshire, and he’s a passionate Red Sox fan. You can see and hear how Jordan got started in Twittering about the Red Sox in an audio/video slideshow that Conaway put together.

And as for the Red Sox themselves? Well, they’re off to a promising 3-1 start and visit the Toronto Blue Jays in a 7:15 contest tonight. I’m counting on Jordan to be at his Twittering best from the game’s first pitch.
