Yes, I read his comment.

""dig @www.facebook.com news.ycombinator.com" does not use the ISP's DNS servers at all"

Incorrect. The program he's using, dig, has to look up the numbers for facebook.com's authoritative servers first. And what DNS servers do you think it uses to do that? The defaults he has set: his ISP's.

"It sends a DNS query to Facebook for Google."

Incorrect again.

The "advice" I provided is not pointless. I would not provide pointless suggestions.
