Today, we have a birthday to celebrate. And then I wound up encountering so many interesting thoughts shared by our terrific listeners that once I had written everything that I wanted to say regarding the emergence of Google's long-awaited Topics system to replace tracking, while still giving advertisers what they need, I'd filled up 18 pages of show notes and ran out of space for other news. So next week I'll catch up with everything else that's been happening. But the topic of Topics is, I think, important enough to have most of a podcast for itself!
