Twitterstorm rising: On Rio eve, sharing a call to end fossil fuel subsidies | Grist

A “twitterstorm” isn’t something out of Alfred Hitchcock’s The Birds; it’s a global campaign to raise a ruckus on Twitter by deliberately spreading a message — in this case, the call to end fossil fuel subsidies, or #endfossilfuelsubsidies, as the hashtag call will go out.

Organizers are building a smart network of influential Twitter users to seed their storm. On the eve of the Rio+20 Earth Summit, they’re aiming to break the record for most tweets of a single hashtag in a 24-hour period.
