I hope next year some more projects move to #tor .onion space. With all the censorship and aggressive attempts to unmask domain name and site owners it feels like he pressure to do so is building.

Looks like Elon's vibe-coding idiots managed to screw up the last remaining good thing from Twitter: the search syntax. Specifically, parentheses. You can no longer build complicated search expressions with parentheses.
Now would be a great time for Mastodon to implement full boolean search syntax.

The anti-vaccine movement has the same talking points now as it did in the 1800’s. It’s always been a rejection of science, scientists, and progress, with a soupçon of paranoia.
Below is a slide for a talk I’m preparing that illustrates the identical strategies. I have more examples, too.

Accuse expert vaccine advisory committees of pro-vaccine "bias"
"That commission was deliberately packed at its very outset..."
"The committee has been plagued with persistent conflicts of interest and has become little more than a rubber stamp for any vaccine".
Falsely state that vaccines cause death
"Vaccination has caused more deaths and diseases than ever has smallpox".
"This [COVID19 vaccine] is the deadliest vaccine ever made..."
Claim that healthcare practitioners and scientists are only in it for the money, not because of scientific evidence
"...Jenner was a mercenary charlatan whose ignorance and impatience of scientific methods were equaled only by his mendacity..."
"Doctors are being paid to vaccinate, not to evaluate. They're pressured to follow the money, not the science".
Use false and inflammatory words about vaccines

1/ A longtime Wired editor just wrote a mush-brained essay about how he totally missed the political rot of Silicon Valley (& still doesn't get it).
But in the late 1990s, a Wired journalist warned of a toxic ideology bubbling up from tech. Paulina Borsook has largely been erased. Let's change that
