Great thoughts!

I do agree it does look very similar to Medium, but one would go to Medium only to write a blog post. But writing on Medium, is a treat for anyone, so I mimicked a similar editor where you can just pour in any thoughts that one might have, and added a bunch of different functionalities that were missing in the medium editor.

Frankly speaking, I had created it for myself as sketchpad over net, but when I showed it to a few around, they liked it so I put it up on web.

I hope that clarifies your point. Cheers!
