I just found out about Branchout. It’s basically Linkedin for facebook. You get to see all of your friends and where they are currently employed (and where they were employed) if they have added this info in their profile. You can also take it a step further and see where friends of friends work.
I didn’t know where some of my friends went to earn money each day, so it was cool to find this out.
I also think it’s a great way to cut down on social media platforms by essentially combining two together. (Not that Branchout totally replaces Linkedin, but close.)
