The 2010 Spring Edition runs from April 22nd to 27th. Most events will be held at a pretty cool venue - the Mayfair Theatre in Old Ottawa South. There are also some post-festival events lined up for May, June and September. The full schedule can be found on the official website.
I think I might check out Terry O'Reilly and Mike Tennant's presentation on Sunday, April 25th. Their CBC Radio show The Age of Persuasion is consistently interesting and Terry has a pretty compelling website as well. If you're interested in marketing and culture, this would be a great event for you. Maybe I'll see you there!
