I dunno, I just personally love What's New, and would prefer not to have to go basically looking at 2 different pages for new content. I understand What's New is specific for forum topics, but... maybe it's a suggestion XF can look into allowing NEW/UPDATED releases to show in What's New. Once the whole convert to the resource manager cools down, we won't be having 10 new resources popping every day, and it will be left with me being forced to click Resource Manager to hope they'll be new resources, but sometimes, it could be a week or two possibly without something new or worth my while.
That in the end would create a bad user experience for me and would discourage me from clicking on the resource manager as much.
