Your social share privacy plugin looks real promising. I uploaded and tried to enable it but I'm getting the following error message:

Parse error: syntax error, unexpected T_DOUBLE_ARROW, expecting ')' in /home/user/public_html/photography/plugins/socialshareprivacy.php on line 75

Suggestions? Thanks.

Thanks, a typo. Fixed. Download the master for now, not the release.
