Several people have posted links to articles, I appreciate that you are
interested enough to post these, but it's unclear what you want me to get
out of them, and they tend to be very long. It would help me, and probably
other readers if you could summarize whether they agree with / disagree with
/ expound on / or amend my conclusion, and maybe a sentence explaining what
specifically we should should be paying attention to, if we invest the hour
or so it would take to read the article.
