Don't let these people discourage you. You are starting up and by the fact that you already got people's attention in HN, that shows that you are onto something greater. Keep the good work!
Really appreciate your comment!!. I am too much of a dreamer (curse or not) and i've dedicated too many hours (3000 aprox) for these comments to discourage me. I love facing criticisms and building from them :)
Cheers!!
