A gentle suggestion for bloggers: if you're going to write an article with a title like "The growth of command line options, 1979-Present", please also arrange to prominently display the date of composition.
Really, any blog post should have a prominent date on it. For a lot of things, it's essential context. Older posts can be useful/interesting but they can also be pretty much completely useless depending upon the topic.
Every article (really, every thing) posted on the web should be timestamped.
March 2020 for those of you who just had to find out after reading this comment.
> The latest year in the table is 2017 because I wrote the first draft for this post in 2017 and didn't get around to cleaning it up until 2020.
