Heritage Toronto was lacking a budget to make new historic plaques, so heritage buff David Wencer arranged a "Twitterthon" to call attention to the 250 plaques that already exist.
Wencer asked Twitterers sympathetic to their cause to use a map of the locations to go visit the sites, then tweet about them, or to tweet about locations where there aren't yet marked but should be.
Kayla Jonas participated in the event:
"Over the weekend 80% of the Heritage Toronto plaques were tweeted about. Many non-city plaques were also spotted and a list was started of places that should have some recognition. About 20 people participated in the finding and tweeting of plaques, but the tweets were retweeted or quoted hundreds of times over twitter. Conversations were started about the plaques, and other places started talking about holding similar events."
