I know of ones who do this though on different platforms than instagram. I imagine instagram would be a fun way to do so though and can perhaps be linked here for others to read. @Ilsabet here in this forum keeps a journal too amoung others.
When I discovered WiX.com I created this to record various notes together with my character's backstory, which I then illustrated with screencaps whenever the game got too laggy for adventuring. (Yes, I have far too much time on my hands!)
