Tyler suggested art bloggers make museum wish lists and mine is simple, radical, and honestly based on the almost 10 years I've been working part, full and intern-y in museums:
free admission
late hours that work with working schedules
missions about education, not money
good pay for museum staff (grumbly curators are grumbly because they can't pay their student loans)
a manadatory job switch for one day each month for all museum staff, docents, and board so that everyone understands what the various roles are
museum leaders should be engaged in the museum not the country club
and if everyone who believed in a museum (any museum) sent that place a check earmarked to the program or a fundamental need (maintenance say, or preschool art education) those programs would be clearly seen and supported.
I've got more to say but no time to say it. So that's that. Hope it helps,
