Mal Fletcher comments on her reign.

Yet, having spoken one-on-one to more of them than any of her subjects can ever hope to, she obviously has some sense of the challenges and opportunities people face.

Among those is a challenge she is perhaps uniquely qualified to address.

An Ipsos-Mori report this week suggested that British adults, as a whole, glance at smartphone screens 1.1 billion times every 24 hours.

That's 28 times per adult over the age of 18 (heaven only knows what the figure is for people younger than that).

We spend an average of 90 minutes per day on non-voice activities on smartphones - three times the amount in 2012. Our conversation, it seems, is via messaging services and increasingly ubiquitous social media.

In much of this activity, we are adding to the databases of some of history's biggest companies and near-monopolies.

At the same time, we increasingly blur the line between what is considered private and what is open to outside scrutiny.

Many of us seem unable to cope with the notion that, at any given time, we are not represented in the collective stream of consciousness that is social media.

In the process of publishing and promoting our everyday activities and opinions, we potentially expose ourselves to identity theft and, even more subversively, the shrinkage of our private thinking space.

As a result, we may unwittingly compromise our self-respect and the respect others have for us. If not outright contempt, familiarity can certainly breed complacency.

Perhaps we should withdraw a little more, thus potentially allowing our opinions to carry more weight when we do have something to share.

The Queen has demonstrated that one can be accessible to the outside world, without pandering to rampant voyeurism. In this, as in so much else, she has set a fine example for us all.
