One of the recent changes to Facebook is the new limited newsfeed feature. You may have noticed that you are only seeing updates in your newsfeed from a few people, and that, whilst the same circle of people are commenting on your news, everyone else seems to be ignoring you. Well, the likelihood is that no one has actually blocked you. "New Facebook" has a newsfeed setting that, by default, is automatically set to only show people you've interacted with recently. Any other friends are now invisible to you and you to them.
TO FIX THIS:
Scroll down to the bottom of the Newsfeed on your HOME page and click on "Edit Options". In the popup, click on the dropdown menu next to 'Show posts from:' and select "All Of Your Friends and Pages" and then click Save.
By doing this, you will receive newsfeeds from all your friends and pages. This will ensure that you will receive important updates about protecting coastlines and the ocean worldwide from Save The Waves.
