No. No indication was given in the 'Ask HN' that any prior area/research related to 'Ask HN' question was done.

As noted in original response above, question as asked is bit broad. 'Enrollment' does provide clues as to level/area(s) of interest

Suggestion was to narrow down the topics to bid more specific areas/subareas of computer science interested in.

High quality recommendations without a 'see course catalog'/google need to have a directed topic(s) focus within computer science.

a) phd level, hobby level, just getting started level, coding challenges (day/week/month/unsolved problems in area of computer science), etc

b) AI, operating systes, database, storage, programming language theory, non-linear programming language insturction, etc.

Again, the search topic was a suggestion to narrow down the very broad/open ended question in order to provide high quality general topics/high quality specific course recommendations.

As a specific different line of thought, search engines can provide way more information on which HN more readily help narrow down -- but that requires something more specifc than field of study.
