Genshiken, Comic Party Recommendations
Like Comic Party, Genshiken deals with the real life world of being a fan. While Comic Party concentrates more on the making of the products, such as Dojinshi, Genshiken concentrates on the people who buy the dojinshi. So if you ever wanted to know what type of people buy Kazuki's books watch Genshiken.
They're both anime about otaku and doujinshi, except Comic Party is based on a VN so it's got a twist of harem to it.
