Meta’s Trojan Horse for the Consumer Internet
When I wrote my “first impression of Muse” piece last week, I promised that I would write a follow-up piece on how I am using it after a month. I may still do that, but after using Muse for the last five days, I feel compelled to share my updated thoughts right now.
Why “Affordable Luxury” Doesn't Compound

DoorDash had a fine quarter with total orders growing ~27% YoY (~17% ex Deliveroo) and marketplace Gross Order Value (GOV) growing ~36% YoY (~23% ex Deliveroo). More importantly, GOV in US restaurant category slightly accelerated in 2Q’26 primarily due to DashPass membership.
Amazon 2Q'26: AWS Gets the Love
In 1Q’26 earnings coverage of Amazon, I mentioned AWS would likely grow by ~35% in 2Q’26. AWS did slightly better than that as it grew by ~37%!
