Alas, after a run of two years, this will be the last Day of Reflection. Look for the newly rebranded but otherwise identical Sunday Digest next week.

I had this question that went unanswered

• What's the history behind the Tarascan yácata? Why is it a "keyhole" shape"? Were they only a Postclassic structure or were there "proto-yácatas"?

Yodatsracist had a great answer for What other prophets were there in the Middle East between 0 and 600 AD that attracted a sizable following?

I'd be interested to see how Germanic peoples were politically organized in this question: What was Germanic society like during 50 BC to 50 AD?

I'd really love to know more about piracy in the Mediterranean

What was life like for women in the Sassanid Empire? received one controversial answer.

Didn't get to read much on here this week, but there were a few things that I liked.

• /u/an_ironic_username second entry on the history of whaling came in this week's Friday Free-for-All (here's the initial post if anyone's interested). I'm looking forward to future installments and I wonder if any other flaired users might try doing something similar.
• /u/idkydi explained why dynamite was not the downfall of the Great Wall of China, no matter what Civilization V may have taught us. It was informative and I love the Civilization series, so I really enjoyed this one.
• /u/yodatsracist gave a monster answer informing us all about the reliability of Ottoman census data and the movement of various populations after the break up of the Ottoman Empire. There are also ton of follow-on questions and answers in that thread that I'm still wading through.

As a side note, just from looking through that last thread with /u/yodatsracist's answer, I think that questions in this subreddit with a very high ratio of comments to votes are probably worth reading either because a) they're in a focused area that didn't draw broad attention but did go very deep, or b) they were posted at an inconvenient time but still managed to stimulate some good conversation.

I also posted a pretty niche question this week and was disappointed (but not entirely surprised) it didn't get an answer:

• How did Oliver Cromwell get along with his aristocratic cousins?

Surely someone out there knows!
