See the "Should my idea be part of an existing site, or its own site?" part of the FAQ. I see little to no point in having a site separate from Mathematics Stack Exchange and MathOverflow. Googology is part of maths so all questions would be on-topic there and Math.SE already has a (big-numbers) tag.
