Yesterday Facebook introduced a new group feature on Facebook’s Newsroom. Facebook groups are the places for similar interests, activities, ideas where your are free to share things with the people having common interest on a particular subject. You can join a group to get connected with the communities, organisations etc.
Now when you visit any group you can view who’s seen each post and you can easily get updated with the group’s ongoing activity. Like in Open Source Council (a Facebook group) if you share a link or may be your blog post then you will see who got its update.
