You don't get the message at all...

Alright; this is how it is. The article in itself isn't a bad advice... If you're writing a novel or are this super-ambitious (and slightly delusional) RP'r and have the time on your hands to rewrite posts constantly without annoying your co-players that you take too long. However, the point of working with multiple iterations is trying multiple approaches, rather than assuming your first idea is best (it rarely ever is). Through writing the same thing twice over, you're actually learning from your first attempt. If you wanna sell a book without jumping on the vampires-are-hot train, this is pretty good advice.

However, the lot of you posted some seriously stupid shit. If you change something after 2 paragraphs, your iterations are far too short and your writing style will likely suffer from inconsistency because you lose the same flow over the course of writing. Too many breaks = bad. Also this isn't about planning, it's about re-imagining and gaining new perspectives through experience. Even if you plan what you want to write (and yeah you should plan ahead probably) this method doesn't lose an inch of it's usefulness. If you think it does, you're either arrogant or stubborn.

Also, here's an edit, because I couldn't help myself.

The purpose and practice of novel-writing are completely different. As Dervish touched on, roleplaying is an activity you do for fun. Or well, most of us. The majority of RP'rs uses it for escapism. Rewriting can be a chore, which means that you're now spending the time you are trying to have fun or escape RL doing something you don't like. Kinda counter-productive, no?
