Greg, there actually is a "followed makers" tab in Super Mario Maker 2. It's stupidly indicated with a ⭐ in the "courses" section of Course World.
P.S. my maker ID is QF1-TRP-KFF. I typically make traditional-ish courses with a normal difficulty rating. Pls follow <( ̄︶ ̄)↗
I'm fully aware of the followed makers tab in Course World; you've been in my followed feed since you emailed RFN with your ID last week. The point I was trying to make was that I would've liked to have everyone in my friends list incorporated into the followed makers feed right from the get-go, either by default or by some sort of simple opt-in.
This is not just because of the cumbersome nature of inputting IDs for people I'm already connected to; moreover there's no particularly direct mechanism for me to become aware of these IDs in the absence of Miiverse (which would guarantee that anytime a friend made a level, you'd see the course ID posted on their feed, and you could then use that to add them into your followed makers in the original Mario Maker's Course World).
I've been relying on rather indirect mechanisms to build my followed makers feed in Mario Maker 2, such as RFN emails and piggybacking off other people's activities (levels played/completed/liked, etc.). As such, I think I have a pretty comprehensive feed in my followed makers tab by now; it's just a shame that it's been such a convoluted process to get to that point, and there is still the possibility for some friends' levels to slip through the cracks because this rigmarole is not automatic in the slightest.
Anyway, please accept my apologies for not being very clear in articulating these points during the episode, and I hope this text has helped to make up that deficit in clarity. Also, thanks for listening and for sharing your levels - good stuff!
