The wall is microblog; a place to archive thoughts and ideas that you want to preserve, perhaps to look back at in the future or to share with others at a later time. It is intended to be a time machine into your mind in the past and a way to share your ideas no matter how random or inconsequential they are.
My motivation for creating the wall
My motivation for creating the wall stems from my enthusiasm to write about ideas that I find interesting. I often do not find the motivation to turn those short snippets in my mind into full fledged written pieces yet I still want to record them somewhere that isn't just the notes app on my phone.
