Earlier quoted context omitted.
> Basically to criticize a piece of work was reserved to a few professional critics writing in newspapers. It was common to write replies in long form and mail then into newspapers, which would then publish them.
That's a good point I didn't even think of, however it may have been subject to censorship and editing by the newspaper staff and would have limited reach for most newspapers, not a global audience. Also I don't think I ever wrote a response to any newspaper in pre internet times, that's a lot of work just to be heard.
It was fun, and I certainly _felt_ like I was being heard - first when I saw my words in print, and again when selected replies would get published a week later or so.
Ultimately, I suppose not so different than posting to $platform_of_choice and waiting for replies/retweets/etc. Just slower.
