“Shonanonnies” were those nonnies in the early days of meme who were inspired by Sei Shōnagon, the author and court lady of the middle Heian period in Japan who wrote, among other things, The Pillow Book. The ultimate Shonanonny was sei_shonanon, who started this early February 2011 thread.

A few other Shonanonny threads:

• Feb. 7, 2011 (not the same one as linked above): A thread in which Shonanonnies wrote //waka//.
• Dec. 13, 2011: Things That Give A Clean Feeling.
• Oct. 3, 2012: If they were shonanonnies...

The Shonannonies became quiet for several years, until someone started a July 2015 thread asking if they were still around, which got 18 comments. Several days later, in the same post, a nonny discussed certain //Pillow Book// translations. However, since then, they have again faded from FFA.
