Waduppp!
Ok now you have given me an app idea for blockchain. You post everytime you poo(ok so let us start by mentioning poo time) and then you have to add something creative you thought while pooing.
OK so a post can be something like:

Poo time: 15 minutes

Idea: An app where you post everytime after you poo.

OR

Poo time: 2 minutes

Poem : OH my poo
Where are you?
