Where are the church social media policies?

The church is not known for responding quickly to cultural
change. But really: almost seven years after Facebook launched, with thousands
of pastors using Twitter, and NPR running stories
on how Facebook and texting may break up marriages, I figured many churches,
regional bodies and even denominations would have developed social media
policies by now.

Yet a recent search turned up limited results:

• The
  Episcopal Diocese
  of Connecticut has some social
  media guidelines.
• Holy
  Trinity Catholic Church in Washington, D.C., shares its policy
  on its website.
• Church Crunch has tips
  on how to make your own guidelines.
• The last PC(USA) General Assembly enjoyed this
  policy.
• A few bloggers have thought about such issues--David
  Pickett, Bruce
  Reyes-Chow--and I shared my personal Facebook guidelines in a recent post here.

Maybe my search skills and personal contacts are more
limited than I realize, but after a few days of searching I found a dearth of
church social media policies. I expect the main reason is that policies like
this often develop because of misuse
and abuse, not before it. So, sadly,
when sexual misconduct by pastors and others by way of social media becomes
more common, the policies will follow.

Please tell me I've missed some policies. Has your church
discussed the appropriate use of social media by pastors and youth leaders?
What standards do you use? Bonus points for links to more policies.
