I like the idea - wouldn't be hard at all to add to the title or at the top of the first post, or something. As I said in the other thread, some members might like knowing their thread is being featured (and will hopefully get more responses that way) and others will be aware that what they say is essentially being linked on FB and Twitter, so they can choose to participate or not - and keep more personal information out of it, if they so desire.
Also, as it was mentioned in TAO, this isn't a new thing since MDC went through the changes - they've been active on social networking sites for some time now. It may be more important now to advertise in that way, but it isn't a super recent thing they have just started doing.
And of course, everything we post here is public to the whole wide world who is connected to the web. If anything, the notification would be nice b/c members could then go on to FB and read the chatter that follows that link on the newsfeed, since that isn't posted here.
eta: the other thing is that with the FB connect at the top corner, anyone can easily link posts on their own personal FB - so I don't know how hard it would be to include a notification of that, too. Even w/o that, of course, as long as you can C&P a URL or some text, our threads or posts can be quickly shared anywhere. But with Mothering having so many FB followers, and conversation there on FB as a result of threads posted here, it would be nice to include a disclaimer on those hand-picked threads.
