I'm on facebook way too much and one of my favorite pages to follow is All-About-Psychology. The authors share many ideas and trivia related to psychology's content and history. Their main website is: http://www.all-about-psychology.com/. You can find them on facebook at this link: https://www.facebook.com/psychologyonline. The author of the page also offers free kindle versions of his work from time to time. It's worth a look.
You will find ads on their site, but they have some pretty good content, just check out the links along the left hand side.
