The original point of Waiwai was to give non-Japanese–speaking readers of the MDN a chance to find out what was in the "non" news in Japan that week. Things that people -- real people in Japan in stores, in beauty parlors, and at bars -- were *talking about*. It was clear from the front it was all tabloid stuff.
And, for the record, I was there, from day one, when Waiwai was first being proposed at the MDN. I was one of the editors of Waiwai, with Adam and Margaret.
