Something that integrates with social networks rather than replaces them could work. Maybe an automated way to setup a Facebook group, G+ Circles, twitter feed, etc. Sort of like a super-blog for churches to make sure everyone gets announcements in a format that's convenient for them.

I've noticed that lots of pastors create a blog, post actively for a few months, and then never post again. 5 years later and there's still a huge link to the defunct blog on the church's website.
