Do we have a responsibility to manage what we say online & the effect it may have on others?

Certainly we expect that professional journalists obey this law and are very disappointed when we find out that the truth has been swayed for publicity. But do we consider that what we post, share and comment on should come with the same discernment and responsibility?

In a day and age where the majority of us have at least one social media channel (Facebook/ twitter/ Instagram/ LinkedIn/ WhatsApp and so on), have you considered why we are on them?
