Back to why I think something like Toilet papers can be the great market is just becuase every single human would like to use it , atleast once a day ;) and upon requirement more than once... though I dont refer to iToliet(Shit on Internet?) as of now, I really mean that coming up with a software that can just be used commonly as much or as much more than a toilet paper ;). Something that a person does everyday and would do everyday that too without fail?
Now let me go back to brains and ask what it is? Would you ind doing the same and share?
