I was annoyed with the injection of my Google+ details beneath every post when I activated the ‘Google+ Profile’ option in the WordPress plugin Jetpack  and couldn’t find any option to actually hide it entirely or change it’s placement. So I hacked it away, effectively hiding it, using a simple divider.
You will want to jump to line 189  in the file ‘gplus-authorship.php’ located in a subfolder of Jetpack (in effect: modules).
I do know it is possible to toggle it with the option ‘Show Google+ infomation with this post’. Perhaps the best practice would be to just remove the entire code block. Probably.
The authorship relation tag is not affected by this.
Here’s a gist of it:
1. Jetpack by WordPress.com http://wordpress.org/plugins/jetpack/
2. Exact position in pico: 189/209 (90%), col 1/30 (3%), char 6562/7082 (92%)
