When searching for an unrelated subject, I found these interesting Hackaday articles about the history of CRT video camera tubes and the history of parking meters. Interesting to see the Hackaday perspective on covering these subjects as opposed to the Wikipedia perspective. I must agree, the Hackaday site provides a useful forum for discussing a concise narrative that would be barred from Wikipedia.
