Essay question?

I have been thinking of essay questions that I would like to write the subject on. As I have been looking at language from artists like Barbara Kruger, I emailed Graham to see if he could help me with putting a question together. He was really helpful and gave me loads of names of artists that I could compare to my work to. But, as I started to write this essay I was also doing some reading for my exhibiting and curating modual on 'Collaborations'. I found this really interesting so I have decided to switch the route of my essay and as I have been working collaboratively with my peers during the exhibiting and curating modual, I think it will be a really interesting essay subject!  

So..... I think this would be a interesting question to write an essay on:


How successful is collaborative art compared with solitary practice?

I am going to do some research into this to get a good introduction together!
