Very much enjoyed Tgiving in Cape Town with BFFs and their (and now our) friends and extended found family--3 Americans and 12 ZA folks total. The latter have enthusiastically adopted going around and sharing what they're thankful for, and they included the holiday itself as one of those things. 1/

I went through every proclamation once. The first to mention the Plymouth colony was JFK. Before the 1940s, the proclamations at most mentioned "an ancient tradition" of thanksgiving festivals.
The first time a Presidential Thanksgiving proclamation mentioned the Plymouth colony as being the source of Thanksgiving was JFK's 1962 proclamation. First mentions of the 'pilgrims' at all are by Truman, became a theme under Eisenhower.

He's got his country's 250th anniversary to plan, a wedding to arrange, a wife to murder, and Guilder to frame for it. He's swamped.

Among the interesting things: Harris voters seem to be more mutually compatible than Trump voters: Females and males have the same #1 and #2, swapped 3&4, the same #5 and #7, 6&8 swapped, etc. Male and female Trump voter priorities aren't nearly as well correlated--no wonder they can't find love.
Trump voting men rank having children as their highest priority in life, and rank having emotional stability dead last. Those poor children.

Here's what I want, and God help me it's a Star Wars movie. It'd be in procedural (maybe even documentary) style focusing on the 6-18 hours or so after Imperial Intelligence determines that the the random farm on Tatooine that harbored the escaped droids belonged to members of Vader's family.
If you were a despotic president, what movie would you force Hollywood to make? I want to see Quentin's Star Trek movie or maybe Kill Bill Vol 3.

Tell you what--I like Baltimore plenty, but it is really interesting to me that Baltimore places higher on this list than Seattle, New Orleans, Houston, Phoenix...

If I lived in Baltimore I'd mention this survey to Philadelphians I knew at every opportunity.

(Dallas, though? GTFO.)

My posts have apparently been pretty bangerous the last few days. Not just a banger to myself but a banger to others.

This website plays all of the departure tunes for each station on the Yamanote ring train line around central Tokyo. Real city heads will want to click Ebisu. Akihabara is the banger you hope it will be.

Yamanotes (/jamanoʊts/) is a web-based music box for playing the departure melodies of each station on the JR Yamanote Line/山手線!

If you want to feel old, we are now further from the formation of the Kenorland Supercontinent than the formation of the Kenorland Supercontinent is from the formation of the Solar System.

I have maintained for a while that a History of Usenet would potentially make an amazing book (maybe it already has), since so much of present-day internet (not just social media) culture has its roots there.
What functionally broke Usenet is that at least some of the bad actors who were spamming were engaging in cancel wars with the cancelbots (message cancellation messages were in and of themselves a special kind of Usenet post w/ instructions to remove a post from a message queue).

Their definition of a comedy is way, way too broad, and there are movies on here that cannot possibly be meaningfully compared (screwball comedy vs rom-com vs live standup set, for instance). I also disagree with their #1, and question the entire premise.
The movie listed at #1 is so incredibly misplaced that it calls into question the veracity of the entire list. It belongs on the list, yes, but SO MUCH further down. An absolute, credibility-wrecking flub. Boo, @variety.com! Boo!
