I've been conducting a little experiment. If I post funny things on my Facebook timeline, or interesting things, all my jw friends comment, like, share etc.
Without fail though, (so far) , if I post something humanitarian, something charitable, some local interest good news story about the community coming together as one, it's VERY RARE for any of my witness friends to 'like', comment, or share. In fact with the latest post, the ratio is ten to one worldlies/jw's!
Speaks volumes eh?
