Those Who Swift - Issue 197
Your weekly dose of Swift!
Weekly note ✏️
Hello everybody! 👋
For those who have been subscribers for years, I have finally migrated you all (hopefully I didn't miss anyone 😬) to Substack.
Curated founder Dave Verwer shared that things had not been going well with the platform for some time now. He also left Curated. Our main reasons for leaving was that there were bugs and other small issues.
As of today, you already received Curated's last email, and next week, we'll exclusively work on the Substack platform.
Our team is already in discussions with creators and conferences so we can thank our community and offer exclusive deals and discounts. Besides sharing news, our goal is to give you something that makes you happy to be a part of this community.
We have lots planned for 2025!
Connect with the "Those Who Swift" team - Justas Markus & Anton Gubarenko 👋
