Here is a 3-paragraph summary of the blog post for mathopen.com:
Mathematician Shaoming Guo announced in a guest post that he and several colleagues are in the process of launching a new mathematics journal. The project grew out of conversations about what principles and values such a publication should stand for, sparking a broader reflection on what the math community truly needs from its journals.
As the team worked through their vision, they recognized that no single journal could capture every worthwhile set of values the mathematical community might want to uphold. This realization opened up a larger conversation about the potential for creating multiple journals, each reflecting different priorities and serving different needs within the research community.
The post invites the broader mathematics community to engage with these questions and think collectively about what future journals could look like. It is both an announcement and a call to action, encouraging researchers to consider what values matter most to them in mathematical publishing and how new initiatives might better serve the field going forward.
