 DGM publishes on @-@ line diaries by Robert Fripp , David Singleton and The Vicar . A moderated forum allows fans to ask questions or to leave comments . Together , the diaries and the fan forum display delayed dialogs in which the artists and fans discuss diary @-@ entries and forum @-@ postings . Fripp 's public writing of his diary has challenged his readers to become more active listeners and intelligent participants in performances of music .
