There's an FAQ answer about the origin of lawns in https://www.reddit.com/r/AskHistorians/wiki/dailylife#wiki_other . There are lots of other postings (like from earlier versions of the FAQ), but I found only similar articles, talking about 18th C England but little about 20th C suburbia.

/u/shayeraaa filled in the gap, and I think the reply is quite good.

Can I suggest here that their reply be added to that FAQ section?

[What is the history of the front lawn?](https://www.reddit.com/r/AskHistorians/comments/8pwkpq/what_is_the_history_of_the_front_lawn/e0f9y21/) by /u/shayeraaa

Or would that be better suggested in modmail?

We're so used to thinking that language has a strong relationship or identity with culture, political unit or subunit, religion, et cetera. /u/retarredroof blew that out of the water with regards to the US Pacific Northwest in 'European colonists often referred to Native Americans by grouping them into categories like "Cherokee" or "Choctaw" on an ethnolinguistic basis. How relevant were such distinctions to the indigenous groups themselves?'

(Please let me know if you think I'm spamming, or if I can improve the descriptions.)

Not a massive effort, but I wrote an answer to a question about ethnic Danish soldiers in the German Army during the Great War which got very little traction, and thus probably went under most peoples' radars.

I got a great answer (with follow-ups) from u/Georgy_K_Zhukov fact-checking an anecdote about unconventional Bolshevik diplomacy...

/u/retarredroof on "European colonists often referred to Native Americans by grouping them into categories like "Cherokee" or "Choctaw" on an ethnolinguistic basis. How relevant were such distinctions to the indigenous groups themselves?"

/u/spiritof454 on "This article claims that what happened in Tiananmen Square in 1989 has been purposefully mischaracterized by the west for propaganda purposes. Is that accurate?"

/u/arte_et_labore on "Is it true that during the Battle of the Trebia River the Roman center, after defeating the Gaulic allies of Carthage, just kept marching forward instead of reinforcing their army? Was this because they were fleeing the slaughter, persecuting the routing Gauls or any other reason?"

The question was "Why was Christianity able to convert the whole of Europe? What about it made it so successful compared to older, native, religions?". I was pleased by /u/talondearg 's answer, that started "But I'm going to explain why I wouldn't venture an answer to OP's question". They then explained about generalities versus particularities.

The points he makes are nothing new, I'm sure -- it's just that I'm not used to seeing the issues mentioned here. Though to be fair, I expect that a lot of such questions quickly get removed.
