How to share passages on an amazon kindle fire
Turn on your amazon kindle fire device.
Make sure you've connected your accounts with the services you'd like to automatically share the passages to.
You only have two options: facebook and/or twitter.
If you didn't connect a certain service upon initial device-registration, there is a way to connect them from the settings on the device. Open up a book for which you'd like to share the passage from.
