"wondering why I should care" is at least passively a toxic comment. At least take the time to click on the link before making a comment like that. Or just ignore the article.
"Never heard of Pando, wondering if anyone could give brief insight into why it's significant?"
Including the abrasive phrasing when it is not needed is toxic and not helpful for polite discourse.

then no one would be quibbling with you.
