From the Ask a Curator website:
'Ask a Curator Day' on September 1st 2010 will open the door to these experts with a unique worldwide question and answer session which will let interested members of the public put questions to museum and gallery curators.
We are using the popular website Twitter to host 'Ask a Curator'. You can find a list of participating cultural venues in the 'who to ask?' section of this website, or simply follow the hashtag #askacurator on September 1st to follow the questions other people are asking.
Ask a curator follows a similar successful event called 'Follow a Museum' which took place in February 2010.
