Hey, this could be fun. I've set up a script that watches twitter for the hashtag '#arisia'. When it finds a tweet with that in the message, the script retweets the message over to @arisia. So, if you're coming to Arisia, and use twitter, add @arisia to your follow list, and join the conversations in realtime with your fellow Arisians!
To have your tweet show up in the @arisia group, just add #arisia to your tweet.
I like your Arisia retweeter. It's been pretty interesting. Any chance you can share the script?
Sure, let me finish with the con, I'll clean it up and repost it.
