I agree. There is no significant value in Notes application alone but what I am trying to generate value in the Hmpgr platform (pronounced as homepager). I have another app called Blog which I am still developing.
I know adoption of these apps are difficult but I do not wish to make them even more difficult by using obscure thing like Textile.
But since you are patiently answering me, can I request you to please go through Hmpgr platform and tell me if you see any value in it.
