Is this corroboration?

Sometimes I don't post things on my blog the first time I hear about them. Even though I want to be trendy and firsty, I see things and laugh to myself but don't save the link. But then the second time I hear about something, the switch is thrown and that subject is now blogworthy. Is this what the "real journalists" call corroboration? Am I now subconsciously operating under the same constraints as Woodward and Bernstein in All the President's Men?

For example, I first heard about Archie McPhee at work a few days ago. Last night, on Attack of the Show, it was mentioned again. Today, it's a post. Maybe that's just the power of serendipity, or that I see the Second Coming as an Omen saying, "Thou Shalt Now Post."

I wonder how many things are languishing in my "news items" folder, waiting for a second mention somewhere to validate them?
