The immediacy of Twitter combined with the ability to tag posts with a subject was exploited in a new way for Supernatural fandom when, in March 2009, a few fans tweeted reports of events at the [[Salute to Supernatural L.A. 2009]]. As news of this spread across fan sites, people started following their updates and tweeting in response.
For the next Con, [[All Hell Breaks Loose Sydney 2009|All Hell Breaks Loose]] (held in Sydney, Australia in April 2009), the Supernatural Wiki asked for people who may be tweeting from the Con to list their Twitter name at the Con page on the SuperWiki. In addition, it was suggested that a tag (#ahbl) was to be used in Tweets, which meant people didn't have to “follow” every individual tweeting, they could just search for tweets containing the tag. It was hugely successful, even though in Australia at the time Twitter accounts cannot could not be updated via SMS from phones, only directly via the internet.
Tweeting has now become usual practice at Cons. By using the tag, fans can not only follow events live from the Con, by using the tag, the search stream also acts as a virtual chat room. At [[Asylum 2009]], the tag #asylum was so popular it hit the trending topics list for Twitter a number of times over the weekend.
