I didn't intend it to be. I advised the questioner to simply do what I did myself : ignore the definition that Mateusz Warcholinski wrote which is open to misinterpretation (as this HN thread shows and Mateusz has acknowledged) and simply go to balsamiq.com.

After studying Balsamiq, work backwards from that to get an idea of what he meant by "wireframe" and whether or not it has "functionality".
