It’s time for transparency about these trade-offs. Dive into my write-up: hackmd.io/HjhzbAu3SkGs...
Are we doing enough to address these risks?

Are there solutions in the works to 'respect' domains that by social consensus belong to particular institutions? E.g. prevent/resolve things like @newyorktimes.bsky.social impersonating NYT.

On the downside, pretty blatant example of how AI can already hide things from us in plain sight
wake up babe, insane new use for ai (generating absurd yet somehow usable qr codes) just dropped
probably one of the few ai-image generation tasks that human artists cannot really do right now

The killer whales, named Port and Starboard by marine conservationists, have upended the food chain in the waters off Cape Town and have already decimated the great white population.

Elizabeth Warren’s Bill Won’t Stop Money Laundering, but It Could Ban Crypto
The Digital Asset Anti-Money Laundering Act that Senators Elizabeth Warren and Roger Marshall are pushing through Congress is the legislative equivalent of a Trojan Horse, writes John Rizzo. It would effectively ban crypto in the guise of fighting money laundering.

I just don't understand how we put up with monolithic social networks design to drain our attention for so long. AT making it look easy!
In simple terms:
This is a starter kit to build feeds like What's Hot, but with different algorithms — maybe posts with over 50 likes, or posts from a specific set of people, etc. Soon, we'll have an in-app feature for you to add these new feeds that people are creating to your own app's tabs.
