I have recently joined an online community “The Episcopal Church in the Province of New England“, or otherwise known as http://province1.org.  It is the brainchild (if I may be so bold) of Sarah Dylan Breuer, the executive director of Province 1 and the author of the popular blog SarahLaughed.net.  One of the recent topics of this site is a posting from Sophos.com, an anti-virus, security company, on Facebook Best Practices for Privacy.  It is a good piece, click through the categories in the menu on the upper right of the page to read all of them.
