Just quickmath with approximate stats. Officially, 0.1% of earth's human population perished to Covid (it was more like about three times that but w/e).
That's a substantial percentage of the world population. A lot of formerly healthy ppl but a _lot_ of ppl with problems society deems non-real.

80 was never a goal, and i really liked the 66 breaking norms of what people expect from a format like this. but once it got to 74ish, i figured might as well fill out the 80. it’s also easier to quickmath %s of creature/lands

Six {So, what now?}

@adhdbusiness.bsky.social

I did a quickmath the other day, and out of 100 items on my feed, only 24 were from any people I follow, or groups I’m in. Of those, half were for sale posts. Of the remaining ones, only 7 were from people I regularly try to interact with.

It’s completely broken.

$16mil for 8yrs just before they won back-to-back titles. Meaning it cost Detroit $4mil for 2 NBA titles.

Charlotte Hornets? Haven't even sniffed the NBA Finals let alone won it in the +35 seasons since then.

Pistons came out of that deal looking like the Warren Buffet of NBA.
