Facebook-Instagram: Here Comes the Flood

That was a tweet from @benhjacobs that I retweeted Monday and immediately got hundreds of retweets from my followers.

For some reason, it seemed to capture the sense of awe from many over the significant milestone.

But it also gets at something else that's amazing in this story. How a small little photo application can be worth so much more -- in such a short time -- compared to an American icon. It says just how important "mobile" is in the business world today.

Monday's acquisition of Instagram by Facebook will have no immediate impact on Facebook's ability to make money from mobile because Instagram itself has no revenue and no plan to charge users. At the moment, Facebook loses money every time one of its users goes through the mobile app instead of the main Web site.
