Upcoming Sponsorship Openings at Daring Fireball 

Weekly sponsorships have been the top source of revenue for Daring Fireball ever since I started selling them back in 2007. They’ve succeeded, I think, because they make everyone happy. They generate good money. There’s only one sponsor per week and the sponsors are always relevant to at least some sizable portion of the DF audience, so you, the reader, are never annoyed and hopefully often intrigued by them. And, from the sponsors’ perspective, they work. My favorite thing about them is how many sponsors return for subsequent weeks after seeing the results.

At the moment, I’ve only got four openings left through the end of September:

  • June 30–July 6 (next week)
  • August 18–24
  • August 25–31
  • September 1–7

I don’t know why next week remains unsold, but that’s just how it works out sometimes. If you’ve got a product or service (or, perhaps, a just-opened blockbuster car-racing movie) you think would be of interest to DF’s audience of people obsessed with high quality and good design, get in touch.

Apple’s Full List of Differences between ‘Tier 1’ and ‘Tier 2’ in the EU App Store 

Apple Developer:

By default, apps on the App Store are provided Store Services Tier 2, the complete suite of all capabilities designed to maximize visibility, engagement, growth, and operational efficiency. Developers with apps on the App Store in the EU that communicate and promote offers for digital goods and services can choose to move their apps to only use Store Services Tier 1 and pay a reduced store services fee.

What follows is a long chart, making clear which features are excluded from Tier 1.

Like I wrote in my larger piece on Apple’s new DMA compliance plans, I don’t think Tier 1 is intended to be a feasible choice for any mainstream apps or games. The whole thing is just a way to assert that 8 percent of the commission developers pay is justified by various features of the App Store itself.
