For those of you who aren't yet on Twitter, I'd highly recommend setting up an account. Twitter falls into the genre of 'microblogging' and is a cross between blogs and chats --in that you leave very short messages (140 char max) and people can reply to you using an "@leifhansen xyz" in the beginning of their message. It's an amazing 'nowsourcing' tool and is growing ridiculously fast thanks to a variety of reasons and being a media darling.
Many people wonder how/why Twitter can work for business, and its a good conversation, but let me point you to one excellent article/discussion on Biznik that already exists. Search 'twitter' in their articles section for more.
Here's a great simple, short video to explain things for you as well.
You can find me (Leif Hansen) on twitter - please say hi and follow me (let me know your AIN connection) so I can follow you back.
Please add your own twitter name to this discussion so we can find, follow and support each other.
Lastly, when tweeting about applied improv please use the following 'hashtags':
#improv for improv in general
#appliedimprov for any applied improv or AIN related info
#appliedimprov09 (or 08, 10, etc) for AIN annual conferences
Enjoy, and I look forward to hearing you on twitter and seeing you at the next conference!

Most practical thought: continuity with what been used. I think the other reason we decided it was that, marketing wise, "appliedimprov" as a tag 'says' more than ain to those who are new. But next year we can shorten it, no biggy ;)
