The original / incorrect title was definitely more interesting than the new / correct version. It's no surprise to me that Microsoft have a number of data centres and a million servers seems believable. But the original title was so far fetched that I was fascinated to read how the numbers were comprised.
But going back to your original question, I wouldn't like to say if you'd have made the front page or not. It would have been less likely - but there's still a possibility enough people might have been interested to up-vote it. If I'm honest, I wouldn't have - but then I didn't up-vote your incorrect title either as I read then vote; and once I spotted the issues, I was put off voting - sorry :(
I've never really understood what drives articles to the front page though. I've read some cracking news items that failed to gain more than a couple of votes but equally I've read some extremely dull articles (and even Twitter statuses) that have made it. I guess it just shows how individual we all are.
