Facebook has unfurled a change that will allow users to see which of their friends has visited and seen posts on groups they are a part of. The change took place last Friday.

However, this change is speculated to soon extend further into the social networking site, making it easy to figure out who has been viewing your profile.

This would affect the over 900 million current users of Facebook and the over 250 million photos uploaded every day, the bread and butter of Facebook stalkers.

Facebook has made no official announcements of its intentions to extend the change. So, though the current changes mean tread carefully, stalk away while you still can.
