From U.S. Department of Education:

The Department of Education announced today that Secretary Arne Duncan will participate in the first-ever #AskArne Twitter Town Hall on August 24, 2011 at 1:30 p.m. EDT. Veteran education journalist John Merrow will moderate the town hall that will also be broadcast live on ED’s ustream channel.

My expectations are low, but I would be happy to be surprised….
