Who's the coolest teenager you know? FBi Radio turned 15 this week and for Thoughts That Count we talked about teenagers doing amazing things, from Marley Dias to Amandla Stenberg.

We were also joined by Emma Rose Smith and Vanessa Lee who are programmers for Unspoken Words, a festival by and for storytellers, with performances, workshops, discussions and special events happening on 7-17 September at various locations around the inner west.

Plus, we spoke to Meriki Hill and Briony Beckett, members of a rollerderby team called Team Indigenous Dreaming who are currently raising funds to go to the Australian National Roller Derby Championships.
