I've played around with Medium, which describes itself as "a place where people share ideas and stories, designed for little stories that make your day better and manifestos that change the world, and is used by everyone from professional journalists to amateur cooks". It also claims that it's simple, beautiful, collaborative, and helps you find the right audience for whatever you have to say.
I suspect that the photo story I chose isn't going to make anyone's day any better, nor will it change the world....but I can attest that it's an easy and beautiful platform to use. I have the feeling it's more adapted to text...articles, essays and such, although the uploading of edge-to-edge images is simple, and quick. Medium recently introduced an app for the iPad.
As to whether it helps me to find the right audience will be tested over the course of the comings days and weeks.
Take a look at my first effort; The Oracles of Kerala.
