That's fair if you don't want to engage because you feel you don't have time, but the spirit of the website is to have an open discussion. That means people will say wrong things. If you don't have time to engage with that....it's totally fine. But just saying I'm right and dropping a large read goes against the spirt of discussion. No one is forcing you to. If you wanted to just do a general response to everyone just make a comment on the main article with your link.

Good luck on your exam as well.
