A couple of weeks ago the broadcaster, writer and academic researcher Vicky Beeching tweeted the question: ‘What do u think of people having multiple Twitter accounts; a personal/private one & public one? Fair enough, or creating multiple ‘selves’?’

I recognise the dilemma. I started my one Facebook account some years ago with the sole intention of promoting my books online. But once the page was in existence and many of my real life friends had become Facebook friends too, the content and conversations became at least as personal as professional. With the original purpose in mind I’ve accepted ‘friends’ requests from people who know me only through what I write, so the page is a bit of a melting-pot of my different selves. Sometimes the obsessively tidy part of my brain would like to unpick it all and start again: perhaps being more social-media-savvy this time and setting up two separate sites.

Most of us would recognise that different aspects of our personality come to the fore as we inhabit multiple roles, engage with people for a range of reasons and purposes, explore relationships with varying levels of intimacy and belong to groups in a different way and for different reasons. We would also recognise, though, that there’s something that ties all of that together, called ‘me’.

Some who responded to Vicky Beeching’s question believe that it’s useful and appropriate to maintain boundaries between business and personal use of social media, even to have separate accounts relating to different areas of interest. One person questioned why ‘multiple selves’ is necessarily a bad thing and another claimed to have more than 35 Twitter accounts, whilst someone else worried that if he had two accounts he would always confuse them.

We are highly complex creatures. Not only do our personalities have many perfectly compatible aspects that are magnified or submerged depending on where we are, who we are with and what we are doing: we are also full of seeming contradictions, and probably some very real ones.

How much of this we reveal to whom and in what context is a constant negotiation within ourselves; it always was, long before social media came into being to point up the issues. Decisions around Facebook privacy options, Twitter presence and with whom we want to be Linked In simply underline the age-old question: How much of myself is it healthy and helpful for me to reveal to whom?

Thank goodness we can be naked before God without either causing offence or risking someone trampling on our vulnerability. A God who, being three in one and one in three, is unlikely to suggest that we unpick ourselves in an attempt to start again and create something more tidy.
