Everybody complaining about SF rent, just rent your apartment in December. Rents are 15-20% lower if you sign a lease in December. Moving to SF in June/July is really stupid.

Nearly half of all long-form LinkedIn posts are entirely AI-generated in 2026. It’s the platform with the worst AI slop problem.

Posting a Claude-banger over and over again, damages trust and causes people to disengage.

LinkedIn has 17,500 employees and X has 3,000 employees.

X has managed its slop problem to 1 in 3 posts.

Will LinkedIn ever clean up the feed here?

Or is LinkedIn the first example of dead internet theory where the only things left are ads and AI generated “cheat sheets”

I hope at least one of the 17,000 employees at LinkedIn are looking at this and not just how to squeeze more monetization out of the feed. Otherwise Elon will win and that’s a world nobody wants.

It’s wild how in 2026 it takes longer to get approved for the Apple developer program than it does to actually code your iOS app!

Exciting things coming from https://t.co/8qlTvss8l0 and https://t.co/CWvLDHTuVZ in the coming weeks!

We’re going to have a month of free learning in August that will be phenomenal!

Anthropic with Fable and Iran with the Strait of Hormuz are basically the same thing

[Zach Wilson @Zachly]

Anthropic is like a drug dealer right now

[Claude @claudeai]

We're extending Claude Fable 5 access on all paid plans, as well as keeping Claude Code’s weekly rate limits 50% higher, through July 19.

Isn’t the remaining World Cup looking awful colonial?

[Zach Wilson @Zachly]

How did 2022 World Cup barely register for me but 2026 is like… absurdly good. I’m sad all this dopamine will be gone soon and I’ll go through withdrawal

[Zach Wilson @Zachly]

Spain, France and England in the final four is so wack. Like is soccer really cosplaying 1750 right now?

This is why Messi must win. It’s old world vs new world and I’m proud to be an American and Argentina is part of America.

@NathanShumate Can you help find me a nice Mormon wife in Utah, Nathan? I’m finally down to repent of my sins, pay my 10% and come back to god.
