His name is Vince Doria, and while you may never have heard of him, he is one of the pioneers of new media. Doria is stepping down as News Director for ESPN, an operation he’s headed since the early days (1992) of what he says has become “a cross-platform behemoth”. Doria is retiring without ever having posted a single tweet. He has a Twitter account, but it was set up for him by ESPN staffers who hoped he would share some of his wisdom with tweets. But he hasn’t. Here is a short but fascinating Poynter article about Doria, who cautions journalists to be very careful about using Twitter, because you can quickly lose your reputation for impartiality. He says “no matter how you cut it Twitter turns out to be a platform for opinion.”
