I remember seeing it back when I was interested in programming language design. I lost interest around 2010 (after concluding largely what the checklist was getting at, that there's no point developing a new programming language), so that would put it in the 2005-2010 period. Ironically, most of the languages I've used in the last 5 years (Swift, Rust, Kotlin) post-date that period, so I was wrong in my conclusion.
