There's a picture of the brick, you mean.

That was not clear to me. Dunno why people are making such a big deal out of "if you want more info, go here."

I agree with you, I immediately understood what they are, but what's the problem with more clarification? I've upvoted you.

Offering clarification is good, shitting on the article is bad.

The article does, in fact, do a perfectly fine job of explaining what a swift brick is. GP could easily have said “I couldn’t quite picture what a swift brick is”, but instead said “article did a poor job explaining swift bricks”, and that’s what they’re getting criticised for.
