I will be back from vacation soon, I promise you!
In the meantime, have a gander back in time once more. In 2005, the Wallace Foundation commissioned a study which came out, “Gifts of the Muse – Reframing the Debate About the Benefits of the Arts” Artsjournal had a week long discussion about the study.
I made a comment on the discussion which I ended up reposting on my blog because HTML links were forbidden at the time. I have to say, I still like the idea I expressed at the end of the post about community arts groups cooperating on a shared showcase space.
