Maybe a random update but TBS has updated its site for a web radio broadcast for the series! It will direct you to Geneon’s website, which is here.
The first broadcast was a public recording at the Tokyo International Anime Fair event on April 2 (featuring guests: Nobuhiko Okamoto, Kana Hanazawa and Yuu Kobayashi) and it will be renewed on April 9th, 2010.
The radio are hosted by Akemi Kanda Ayumi Fujimura and Kazuyoshi Shiibashi. You can send in your thoughts or participate in the segments of the web radio (Serifu Jingle: send in your imaginary(?) dialogues of what Misaki and Yukimura would say and Ano Hito wa XX-sama!: where you can send in entries of people around that resembles the characters of the series~)
