People really write stories just for themselves?
I feel baffled-- writing is hard work, whereas picturing things in my head is easy, and can be done in endless variations. I write only in order to be read. The self-insertion fic in the Harry Potter universe would actually be made much more difficult because I have to write it for the other two people I'm inserting... if it was just me, I'd change the name and no one would know, but this would actually be a collaboration, making things much more complex, and then there is the question of would anyone else want to read it. I really don't want to bother committing to paper that which does not have an audience.
So, tell me, why does a peerson write it out if they don't care if anyone reads it? As a record of their imaginings? I'm seriously curious.
