Equaldex.com: Logo

Logo concept for Equalitopia.com (name changing, but it still begins with an "e"), a personal project I've put on the backburner for a few years. Hoping to pick it back up and get it launched. I've sketched well over several hundred different logos for the site and this is the closest to satisfied I've been.

Summary of the product:
Equalitopia is a collaborative knowledgebase of the LGBT (lesbian, gay, bisexual, transgender) rights movement, including laws, rights, and public opinions.

Direction for the logo:

• The = sign represents equality. No other symbol is as recognizable for the movement.
• I wanted a circular logo because the application is focused on the world and its progress. Maps, countries, and regions play a major part in the app as it's currently built.
• The inner portion of the circle represents a brain, data, and knowledge.

Would love critique!
