Jesse and Joe will be talking about Twitter (http://www.twitter.com) and the role it's playing today in communications. Everything from friends and strangers tweeting to corporations such as AT&T using Twitter to let people know about a cable outage.
Related to Twitter is tinyurl (http://www.tinyurl.com) which can give you a URL for reference that won't eat up all of your 140 Twitter characters. Recently there have been some concerns about tinyurl security, and we'll talk about those as well.
