I was asked the above question over lunch at a meeting of tax practitioners. I was a bit surprised, but on reflection the guy asking is an employee. He is engaged to work on particular clients and tasks which are assigned to him. He does not understand what it is like to run a business. He keeps working at the coal face.
For those of us who work for ourselves, we not only work at the coal face and engage others to do so, but we have to sell the coal. Otherwise there is not much point in digging it out. We need customers.
I do not claim to be the greatest user of Twitter for business purposes. It is an important part of my marketing – not advertising because we do not use Twitter for that, do we? Interacting with my Twitter contacts means I can give business to others in order to receive. I can point people towards useful information. They might remember that information later, and remember me.
Marketing is one of the issues we manage in running a business, so we have to make time and also bill our customers enough to give them good value and make a profit.
Put like that, I think we all should be finding time to make a profit. Twitter is part of that, but try explaining that to an employee.
