Poynter: Fact-checkers are among the top sources for X’s Community Notes, study reveals. “When Meta CEO Mark Zuckerberg announced the end of the third-party fact-checking program on his company’s platforms, he said he would ‘get rid of fact-checkers and replace them with Community Notes, similar to X.’ But a new study shows that fact-checkers remain an essential part of X’s program, […]

The first couple of #CommunityNotes on this #tweet are unhelpful to the point of probably being counter productive?

That #infoGraphic shows the number of death in the vaccine and placebo groups are identical to within rounding error, THEREFORE there are no vaccine-related deaths.

After they change it to open label, there's no deaths in the placebo group, probably because almost all of them took the #vaccine when offered?

I also checked that #HIV rate - that's half the background rate per year for the #USA

#transphobia #TwitterCommunityNotes

Is this a supportive #CommunityNote with a very unfortunate editing error leading to "neither" instead of "both"?

Or is #transphobe #grammar reaching strange new levels of unintelligible contradictions?

Please rate or write some #twitter #CommunityNotes on this #climate denial rubbish from #OneNation senator #MalcolmRoberts

#CommunityNotes  https://twitter.com/i/birdwatch/t/1559797262678720514 Link goes directly to the community notes, which are currently all stuck on "Needs more ratings - Not shown on Twitter"

#Tweet  https://twitter.com/MRobertsQLD/status/1559797262678720514 Link goes to Mal's tweet in the usual twitter interface.

I am not sure if the ratings count if you have not signed up for #CommunityNotes or have not been accepted yet … but it is worth a try?

And you can sign up via the "join" button on that page.

If the first link doesn't work (or you don't trust my links) you can also sign up for #CommunityNotes via the link in the pinned tweet on their official page  https://twitter.com/CommunityNotes

Unfortunately there seems to be a long waiting list.

You can follow the @CommunityNotes twitter page Mastodon via a few different mirror bots. These are unofficial mirrors, they don't send any comments or likes back to twitter. But a lot of instance admins block these twitter mirror bots because they create too much traffic, or cause confusion by being mistaken for profiles of people who are also here on Mastodon.

Can anyone identity what these videos actually are?

Obviously his central #ConspiracyTheory is #nonsense but I'm curious about what the images actually are.

Particularly the jet spray? it looks like too much for a crop duster but not enough for fire fighting? Are they testing a #FireFighting #aircraft maybe?

#TwitterCommunityNotes

If notes get rated as "Helpful" they are displayed under #tweets

"Helpful" ratings ALSO mean that #CommunityNotes author is able to write more notes on more tweets

"Unhelpful" ratings hide that note from further ratings and reduce how many other notes that author can write.

So ratings on notes don't just affect that note, they create a feedback loop of more or fewer notes like that.
