When I first heard of RIM’s plans for the BBM Social Platform for developers the first app idea that came to mind was an app for BBM users to find other like minded BBM users to chat with. App World reviews have long been abused as a way to post your pin to find friends but Tafasa aims to change that with their free BBM SDK powered Smoothie app.
With Smoothie you can enter the Blender and find another random person to chat with. Alternatively you can specify further by setting age, gender, location, and interests so its kind of like AOL chat rooms circa 1990s. You can join group chats in the Coffee Shop section of the app to discuss things like Sports, Games, and Food and break out into single chats from there.
All in all it is a pretty slick app especially considering it is free though it requires OS 5.0+ and the latest version of BBM6. You can pick up Smoothie free in App World.
