Hmm... Just my opinion, but seems like this could set up kind of a nasty atmosphere, actually. Part of what's necessary in a community is the ability to vent safely about other people. It's infinitely healthier to do that than it is to either let things fester or to commit various acts of vengeance. It's also true that, in general, people become more able to cope with this idea as they get older and more secure in themselves. I rather hate the idea of someone discovering they've been talked about in a locked post and thinking the worst, possibly ruining friendships before discovering that the post in question was about planning a lovely surprise for them.

I'd be interested in knowing if, in all honesty, there is anyone who absolutely wouldn't experience any anxiety at all if they discovered they'd been discussed, and had no access to that discussion or ability to speak up for themselves. Hasn't that sort of thing been at the root of uncounted thousands of dramas and rifts through the millennia? Personally, I've never been any sort of fan of Big Brother, but Little Brother can be even worse, especially when fueled by tech produced by a conglomerate that basically wants to enable everyone to peer into each other's pores without permission.

I hope that Dreamwidth rethinks this, or at least gives everyone the ability to block GA's usefulness in finding their journals and posts. Making any part of a friends-locked post public against the will of the OP, even as indirectly as this, poses a serious ethical issue for me.
