The point being made is very strong. The person sending an article SHOULD be obliged to send their own additional thoughts along with a link!<p>Sadly, non-technical people simply WILL NOT attempt to understand what they're reading. So the real question is not the etiquette of the sender but of the receiver: do you HAVE to summarize and explain the content to the person who sent it to you?<p>I think the title of the article would be stronger if it were more generalized since this happens to ANYONE with a well-known area of expertise such as mathematicians, scientists, fans of book series, beekeepers, etc. I can't even imagine what nutrition experts have to put up with from friends and family. :-)
