OP here. It turns out it was explained back in 2013: https://news.ycombinator.com/item?id=7357580

For some reason, I got my dates mixed up. At one point, _why did publish something post-2009, then went silent. I thought it was back in 2013, but it was earlier than that (between 2010-2012). Then in 2013 people discussed the new Wordpress site on the domain.

It was a problem with my memory, not with being too lazy to "site:news.ycombinator.com whytheluckystiff". Sorry for the mix-up.
