You're kidding right? Blogger is the Edsall of the internet.
He could have put a "publish on" date in and the program burped or something.
Anyway, what's your point? All the author said was that he didn't finish all he was going to say before his post, for whatever reason, got published and that, therefore, he was going to come back later and complete his article.
My point is he published it.... Then maybe had second thoughts.
