Collected data could be shared with third parties.

Instagram on Monday moved to calm concerns among some users about a proposed change in the way content appears in their feeds.

Periodically, a blatantly silly idea gains currency, spreading throughout society, and it has one of two effects: Either it scares the heck out of people, or they become enraptured with its seeming plausibility. Last week, The New York Times published a piece set as a dialog between two economics writers, titled, "A Future Without Jobs?" I thought it fell into the silly category.

I hate the idea of chopping our population into generations: the Greatest Generation, the baby boomers, Generation X, Generation Y, millennials and so on.

It also results in people projecting ideas -- often romantic ones -- onto huge groups of people.

My favorite Boston FM radio DJ was Charles Laquidara, who would end his show with the words, "If the creek don't rise, if the good Lord's willing, if there ain't no meltdown, we'll do it all over again tomorrow right here on The Biiiiig Mattress!" It impressed me that even one day out, he'd caveat his prediction of being there tomorrow. Unlike my hero, I will attempt to forecast the year ahead.

At this time of the year, there's a clamoring among the business publishing class for predictions. That is partly because prediction stories are considered easy to write, and once they're done the staff can go celebrate the holidays while their publication continues to deliver content. However, having written a lot of prediction stories in the past, I can tell you that they are not easy to write.

The company has been searching for ways to monetize the patronage of the roughly 500 million logged-out users per month who hop off Google for a moment to read tweet or two.
