Fascinating.
This is true. But for the record, except for things removed by the author or in violation of rules, everything published on Medium since inception (10 years ago) is still accessible at its original URL (or it redirects if the author set up a custom domain or subdomain), same with everything put on Twitter (for 16 years), and even everything published on Blogger (if hosted on blogspot.com)—for 22 years.
Yes, the fundamental tension, not only in strategy, but in business and, perhaps, all endeavors. Innovate or optimize.
That's amazing
Good perspective!
