there is no real reason for it
With respect, you do not speak for WebmasterWorld (and apparently joined three days ago).
WebmasterWorld is entitled to run the site as they see fit, but the question has been asked in the Community Center Forum and surely deserves an answer from someone who knows.
Why do we have a Google+ button on every page?
