I've found that when these journalism Twitter disputes about who deserves credit for a scoop erupt the most prudent thing to do is give me credit because even if I didn't have it first I probably would have if I weren't doing other crap.
There's been a lot of journalists calling other reporters, news outlets out on Twitter lately for perceived wrongs. I've been guilty of this in the past, too. It's part of this ridiculous "us vs. them" competitive mentality among local media. It hurts us all.
