Where are some places where there is a lack of audience-sourcing?
The surprisingly major empty space for audience-sourcing is in online museum websites. As far as we know there is not one museum that allows commenting or feedback on individual works of art in their online collections or exhibitions. Thus for the time being art and sculpture produced in the traditional manner have very little audience-sourcing. On the other hand the newer Internet-oriented artists collaborations do very much support audience sourcing. Examples include event deviantart.org and rhizome.org.
