Here's a tweetstorm from

I wonder how much of sneezing is actually amplified by evolved viruses that *want* you to sneeze so they can spread.

Specifically: 1. Smart phones reduce the social skills of the entire generation, which causes diffuse mental health impact via peer to peer interactions. 2. If you aren't using smart phone today, you're missing out on a lot of social activity.

A lot of studies show surprisingly little negative impact of smart phone usage on teen mental health. I wonder if there's actually a strong cohort effect that these studies are unable to measure.

Acknowledging great-circle distance stuff, this still helps frame why everything feels so far away in California. We're on the edge of the Land Hemisphere.

This
@vgr essay is probably meant to be over the top and therefore kind of wrong, but it is still very entertaining. ("Mook" is his term for folks who fight a lot of battles on the internet.) https://www.ribbonfarm.com/2020/01/16/the-internet-of-beefs/ …pic.twitter.com/wmU6bk6avl

Great thread and blog posts from
@Chris_Said who looks at A/B testing using the same profit-maximizing perspective that@marketsensei and I use in our Test & Roll paper. Compare our plots of test size versus profit: https://twitter.com/Chris_Said/status/1215733430085804032 …pic.twitter.com/IgtOau5kol

I love it when the world converges to similar best practices from different angles. Like reading two elegant proofs of the same theorem, each proof adds insight and wisdom. Test & Roll ftw.
