In the nature of constructive feedback, I have derived tremendous enjoyment from sharing thoughts with the Substack community, though at times I have found it frustrating not to be able to comment unless and until I pay to do so, which would run up costs considerably if I have to be a paid subscriber every time I wish to comment. I have therefore, with the exception of about 10-12 paid subscriptions, unsubscribed as a free subscriber where I'm not able to comment unless I pay to do so.
