I recall earlier this year there was a large discussion about "International Art English" (IAE) on some of the mail lists - on empyre-l, nettime-l, and articles on triple canopy and hyperallergic & the guardian newspaper site.
there was a conference held this year on the topic also — "Critical Language — A forum on International Art English". I've posted the blurb below for reference. I've asked them if there was a recording of the sessions to listen to. will add links if they reply.
some other articles about it:
users guide to international art english — on the Guardian website
When Artspeak Masks Oppression — on hyperallergic
International Art English — on triple canopy
Grayson Perry talks about it in the 2013 Reith Lectures
