I envisage a near future of infinite competition with the barriers to entry getting lower and lower as time goes by; opening the flood gates to average Jo and every man and his dog and a passion.
I think the only strategy to counter this is to work on a topic you are madly in love with - or maybe we could call it the churn strategy, ie not being afraid to just keep churning out interesting well thought through content pretty much for the rest of your career... in other words if you take your eye off the ball you are vulnerable...
What is your strategy?
