Axis.org is an organisation in the USA which specialises in ministering to teens, their families, and those that work with them. You can sign up to their weekly email – The Cultural Translator. It lists the latest trends in social media, pop culture, technology and any other issues that are relevant in the lives of teens.
Our culture here in NZ is heavily influenced by American culture, so it is a great way to keep up to date and maybe even ahead of where your kids are at.
I highly recommend signing up to receive their regular emails and best of all it’s free!
