If you think Facebook has converted many to stalking their friends or person, here is one more feature that they can “enjoy”. Facebook Group will be able to show you who had seen the post. If everyone in the group has seen it, it will show “seen by everyone”.
I hope Facebook can stop probing further. Imagine if you can see who read your Wall posts and etc. Do you think you want such a feature. Many prefer to keeping their reading habit a secret.
BTW, I don’t see this new group information in Singapore yet. Let me know if you have already seen it.
