On purpose

[Mark Knowles]

There is a simple counter argument to the just for fun hypothesis :the existance of multiple scribal hands indicating this was a joint project.

I don't think I actually used the word "fun" as this does tend to imply a lack of seriousness. Something can be done for pure pleasure, but still be a serious undertaking.

Nevertheless I don't see a joint project as being something that cannot be done by a group of people for their own pleasure. I knew people who would play Dungeons & Dragons (or equivalent) in a group for many hours at a time.
