This is so reflective of my experience with failed machine learning initiatives
No data at all, no willingness to invest in annotation, no budget for the compute, no support integrating into the backend, no capacity to surface results in the UI, no tolerance for monitoring quality, and so on

My whole PhD ended up being about online amplification. Really cute to look back and realize the first sentence of my first paper during my Masters before I even knew what I was doing has the word "amplified" in it

Getting there. I always forget how much configuration can be done for plots, which means long function signatures
The "autoscale_axes" is the most deceptively simple bit. Most of the tricky work on the bar chart is automatically adjusting the axes so that the word labels fit

this is objectively the worst kind of citation format. I feel attacked when I see it

If you use CPM, you can interpret its parameter as finding communities of a certain density. You could start with a low density general communities, and then iteratively reapply Leiden with a higher parameter values to get more dense subcommunities

It took 1 min to find these replies to @schumer.senate.gov on X for his Memorial Day post. Conspiracies, anti-Semitism, homophobia, and mockery in the "top" replies
I have a hard time believing politicians aren't on Bluesky just because they're getting "yelled at" in the replies here

Another place X unfortunately leads Bluesky on "verification" is through "affiliates," accounts that a verified government or business account has verified itself are affiliated with it
They get a custom icon that points back to the account that affiliated them

I think the idea of an all powerful Blue Check verification is a bit dated and it's disappointing to see Bluesky chasing it
Even X has multiple types of verification now. Of course their blue check is infamously useless, but they have a grey check for government, and a gold check for businesses

The reporting pipeline on Bluesky is... Not Great
If I see a post literally advocating for someone to be murdered, I should be able to report it for "violent behavior"
"Anti-social behavior" is too broad, it's more than someone using a slur. "Illegal and urgent"... It's urgent but is it illegal?

Why doesn't Community Notes work without fact checkers?
It was never meant to be standalone. It's meant to be part of a swiss cheese model of misinfo
@leticiabode.bsky.social @ekvraga.bsky.social
It's just one layer. It catches some things, and misses others

The default Bluesky Moderation service has 22 different labels for posts and profiles, but you can only report posts/accounts to Bluesky for 5/3 categories, and these categories don't align with the labels
This makes it hard for users to file reports, and I'm sure it slows down Bluesky moderators

Progress! I got Ozone up and running using my (new) domain and an instance from Digital Ocean
I mostly followed the steps here, which were very helpful
github.com/bluesky-soci...
Next step is actually figuring out how to label things... can't figure out how to do it through reports or Ozone
