The subscription model is little bit confusing (at least for me) but other than that it is really good. It's nice to validate some of the assumptions that I've made before about some UX choices. Good Job!

Decided to test those UI ideas more openly with a little help from the community. Still looking for more a/b tests to write about if anyone is willing to share. :)

@ashok. 100% Thanks for sharing. It should clarify once more content is added.
