It seems strange to me when people write about, ‘On Facebook’, or, ‘On Twitter’… or, ‘On Social Media’. I think it lends itself to the thought that people are above it. As if they have no responsibility for their actions and reactions, as well as what those reactions and actions cause.
In the same way, I’m not sure that ‘in’ social media is much better, because that lends itself to a thought of powerlessness – surrounded by.
Which is why I write, ‘using social media’, or, ‘using Facebook’, or… using whatever. These are tools, and unless Thoreau was correct about men becoming the tools of their tools…
We use tools.
So it may be semantic, but it might be powerfully so.
