Posting links to XKCD like this is generally considered to be a low quality post, hence the downvotes. I’m not one of the downvoters, but thought I’d share the reason as nobody else did.

Edit: gotta love HN! I try to be helpful to someone else that was downvoted to heck with an explanation of why that was the case (based on past replies I’ve seen) and now my post is the own with a negative score. Cheers y’all!
