John Mayer using Web 2.0 to connect to his fans

John Mayer's touring this summer, and you can keep up with him through the interactive community on his website. After reading about this on David Allen's Social Media Today post, I took a chance to check it out. The summer tour is being promoted by Blackberry, who is already deep into interactivity with their phones. Mayer has a blog he regularly updates. In addition, after each show has taken place, a webpage is updated with the set list, comments on the show, and photos, for example, the Milwaukee show.
Web 2.0 and communities are all about interaction. Mayer's given fans a reason to keep coming back to his site, one being that fans are able to vote on a song in the encore for each concert.
