It seems that what appears as 'contemporary art' is going through a period of formal diversity in the 'work' that it contains. This is obviously welcome, but perhaps also works to mask something else. There appears to be a massive wave of rigidification of the available roles within this art matrix. Artists are artists.
Critics are critics.
Curators are curators. Galleries are galleries. Artists, for instance, very rarely speak now and don't think in public about the work they are doing. Under the cover of formal diversity, a series of very strict apportioning of roles is occurring. This seems to be the opposite of what happens when the most exciting and inventive work is being produced - all the categories get muddled or abolished.
