That would be great (unweighting bluechecks) but they actually plan to go in the other direction: Starting April 15th non-bluechecks won't show up in the "For you" section (the algorithm timeline) at all. Unpaid users are being written completely out of the algo. https://twitter.com/elonmusk/status/1640502698549075972

I believe LeBron James said recently he isn't going to waste his money on a blue checkmark, so it should be interesting to see what stays and what goes.

Most of the major news outlets are not doing so either. The Elon stans are crowing that this will be the long-overdue end of legacy media, but it strikes me that the new 'blue check twitter' might end up becoming even more of a social bubble than what it replaced. There are so many low quality accounts sporting a checkmark now that users who value substance will soon be incentivized to just block anyone they find annoying.

Great! But nothing is going to change until people realize that the problem is the feedback loop . It's not the recommendation engine itself, it's the fact that there's no way "out" of the feed that the engine produces. It recommends you stuff, you have little choice but to engage with it, and then it trains on that information . This is the problem with most of social media today. It is a very well known problem in…

I think Instagram in particularly is bad in this regard. It seemingly becomes convinced that I care deeply about the subject of any post that I even momentarily linger on.

Squashing the commit history before releasing it was an interesting (and completely predictable) decision.

It doesn't seem particularly interesting? I would never make a formerly private repo public without first erasing the history. There's no upside to showing everyone your work in progress and almost unlimited downsides.

There’s no way everyone had the same weight in all the recommendation config files.

It’s not about hiding old work, but changes just before making it public.

I wonder what the "author_is_elon", "author_is_power_user", "author_is_democrat", and "author_is_republican" labels are for [1]. [1]: https://github.com/twitter/the-algorithm/blob/main/home-mixe...

Elon is addressing this in the Twitter Space right now. "It definitely shouldn't be dividing people into Republican and Democrats; that makes no sense[...] you've identified something we should be getting rid of right away."

Well someone just asked about it in the live spaces[1] Elon is hosting and he said that should not be there. An engineer said afterwards it is just for metrics but then Elon chimed in again and said "we should get rid of it, it should be gone."

My main questions: Will these repositories be used in production by Twitter? Is this now the mainline, not a semi-regularly-synced mirror?

Musk said that releasing the algorithm will initially be embarrassing, but that they will quickly update it. So it seems that means they intend to at least regularly publish newer versions.

Of course it could also be that they change their mind when spammers abuse the openness.

LeBron doesn’t get $84 of value from Twitter? Definitely not a political statement going on there.

Like it or not but it's the twitter that gets value from celebrities. How many people are on social networks jusy so see what their fav celebrites are doing?
