Facebook is a tool: it's not boring, it's not exciting, it's not sad, it's not mean. The opinions, comments, questions, concerns, pictures, videos, information, you read on Facebook are created and shared by humans from all over the world via their computer or mobile device.
Once you readjust how you look at Facebook - a tool - you will then see the value in it and better able to utilize this tool, that Mark Zuckerberg gave us, to your advantage or your disadvantage.
It's fascinatingly valuable. Example: I remember newspaper ads in the Amandala for pen pals. Now you can connect with some from any country and learn about them, their country, their culture.
Figure out what you want to build with this valuable (almost) free tool.
