My only question about the Rough Drafts group is about data persistence...
Google watches us constantly, and changes to Biznik are quickly found in Google.
That means imperfect, incomplete versions of your writing will appear in Google, alongside the finished versions of the same work.
In fact, if you get a lot of feedback on a work in progress, I could see the unfinished work ranking higher in the Google results than the finished piece!
So the knee-jerk reaction is to NOT post unfinished work to Biznik.
However, the conversation around improving an article is of value to the larger Biznik community, not just to the author. One can learn valuable lessons by reading the critiques of other peoples' work.
So the critiques themselves have a value, too.
Where does that leave us?
Does having in-progress versions of your work visible to the world scare you?
Or do you feel your learning experience can help others to learn as well, so you are comfortable leaving that work in the open?
It is an interesting thing to think about.
And one final note: Why don't the existing writing-focused Groups fill the perceived need already?
