Mark Simonds was in Portland last week for Web Visions. Between all the great sessions and networking taking place, we spent some time with him to talk about Twitalyzer. http://twitterroadtrip.com/journal/2009/5/25/interview-with-twitalyzer.html

Mark is doing a nation-wide road trip interviewing companies and individuals that are on Twitter or using Twitter as a corporate communication tool. Of course, you can follow Mark on Twitter at @route140
