Really? The thread gave updates on the leaders, of which Cain was one, they gave results with names of the two in front. Ignoring everyone else would have required a post that mentioned MC and no one else. Your comment is silly.
Wow really big surprise that letsrun would post a thread about Cain and COMPLETELY ignore the two great runners who SMOKED her today!
As for declining the interview, seems it would have been a good idea but athletes do that all the time - professional and otherwise. If she wasn't happy with her race - she would not be the first to not want to talk about it.
