Knitle lets you share stories of activities you performed with your friends, for free. Each activity that can be "performed" is represented by a QR Code. Anyone can create an activity. Activities may include "Liking", "Following", "Tweeting", "Buying", "Paying", and more. Performing an activity is as easy as taking a picture.
We are currently working on web and mobile products (including SMS-targeted products) that would enable users perform these activities with great ease. Also, we are creating APIs that would allow developers all over the world to design templates for various activities that can be performed on their platforms.
We strongly believe in the fact that every object in the world can have a web presence for activities.
These ideas are applicable to the world over.
