Photo stream - commenting not showing up as notifications

[biosci]

I created a photo stream to be shared. If the other user comments, I see the notification of the comment. If I comment, they do not despite the fact that the notifications for commenting are set to On etc etc. It's nice that in iOS 7 you can now both add photos to the stream.. Nice addition.

Anyone know anything about the commenting?

Anyone? Commenting on shared photo streams? I'd rather not be a part of Facebook so it would be nice if my private circle if friends viewing the photo streams could see comments as they happen by anyone.
