[Darth InSidious]

Err, maybe. At the moment, though, a lot of the "diary" would be:
"sat around and bashed head against the wall, asking why I had cursed myself to endless frustration by beginning this blasted thing", or "tried [x]. It failed. It shouldn't have done. Damn the world.".

As to a tutorial, a better person for writing a tut on new planets would probably be RedHawke, who is rather the father of planet mods (and the only person to have released an entirely new planet within the original story to date).
