@evan I (mostly) don't think social software should default to showing replies with special treatment in the first place. But the "original poster" (author of any given post) should be able to *add* replies to their post.

I'm not sure if this makes my position a "qualified no" or a "qualified yes", but I'm gonna go with "yes" because it makes more sense to say that if you can explicitly add a reply, then you can explicitly remove it as well.
