iMore is part of a family of Websites, which include Android Central, Windows Central, and CrackBerry. The post count here at iMore is the top number, the second number called global posts represents ALL of your iMore posts combined with any posts you have at any of our other sites. In your case you just have posts here at iMore so your counts are the same. BUT if you look at me, or @Spencerdl, you will see our counts are different. I have 5k posts here at iMore BUT 45k posts at ALL of our sites. Spencer is 30k here, and 43K at ALL the sites.
