Thanks for this series, I have enjoyed it. I had some questions regarding your process, but you've basically responded to all of them in this post.
I have also enjoyed the acerbic tone of some of the articles. Did it seem over-the-top at times? Who cares! As we say around here - a good hate is never bad. 😁
I wondered whether you'd get to .NET or LINQ. Well, maybe in the next one. 😁
Also, two interesting esolangs in case you or someone else reading this don't know them are Piet, which is basically a 2D language with pixels, and Rockstar, which makes programs sound like metal songs. Dylan Beattie, the author of Rockstar, has a fun talk where he talks about both here: youtube.com/watch . He also talks about other things - it's a really good talk.
