Well, I for one could use a little fame.
I think that the "real" art world is quite personal and artists who are "in" really get on without a lot of hullaballoo or tooting their own horns. Collectors, galleries, and brokers know them and their work and seek them out. It really makes sense because they know that they can depend on the artist to always come through with good quality work and it becomes a matter of a great business relationship developed and nurtured over time.
The rest of us toot away with the hope that we will get "in" someday too.
Quality and reliability are the key. My two cents worth.
