I think we have to understand 'editing' in its full sense--i.e., not just cutting but the process of thinking and rethinking one's ideas with the help of interested and/or informed others (the headline's "snip snip" does lead us to the think of the former, I'll grant). Editing a manuscript, for instance, involves suggesting ways in which to help the author's voice sound its best, not just lowering the word count. The article gives a great example of collegial advice-giving--Robert Raushenberg to Trisha Brown, so yes I agree that it's best to have a trusted and/or famously insightful advisor Leigh, you seem to be a reasonable choreographer who is literate and listens. Most choreographers, in my experience--with some wonderful exceptions--don't hear a thing, and bank heavily on the lonely struggling artist thing. What's worse is that no one whould *think* to say anything to them. What I wish the article had time to get into is the lack of a mentoring or apprenticeship period for a young choreographer. Sometimes it seems as if any former dancer--especially with a major company--is allowed the privilege of choreographing for a full company too soon (or directing a company--but that's a whole 'nother thread!). Balllet seems especially prone to this.
Finally, I'm not sure, Leigh, why you think workshopping is inherently a bad idea. After all, nothing obliges you to accept any suggestions, and you could configure the constituency of the workshop as you like (perhaps, say, a group of like-minded choreographers at a similar career-path level, or artists or musicians that you may know. Or--horror of horror--dancers!). Can you say more?
