Sondheim co-moderates several email lists, including Cybermind, Cyberculture and Wryting. Since 1994, he has been working on the "Internet Text," a continuous meditation on philosophy, psychology, language, body, and virtuality. His artwork can also be found within Second Life. In 1996 he was keynote speaker for the Cybermind96 Conference in Perth Western Australia - one of the world's first conferences specifically organised around an email discussion list. In 2012 he was a presenter and active participant at , a one-day online symposium on cyberformance. Sondheim is the developer of the concept of codework, wherein computer code itself becomes a medium for artistic expression. His poetico-philosophical writings deal with the notion of embodiment and presence in cyberspace, loosely based on the work of postmodern philosophers Jacques Lacan and Jacques Derrida. He explores notions of the 'abject' in the masculine and feminine online, and more recently has dealt with the machinic using the language of computer code to articulate novel forms of identity in cyberspace. His work crosses over between philosophical explorations and sound poetry and more recently he has returned to the language of music using the tonalities of a wide range of ethnic instruments. His poetry has spanned several decades ranging from avant guard beat poetry and stream-of-consciousness of the late 60's and 70's and soundscape poetry, maturing into a complex melding of multiple representational forms. As of mid-2009, Sondheim is working on a book examining the phenomenology and foundations of the analog and digital, and another on developing an aesthetics of virtual realities and avatars. His current areas of exploration include: the aesthetics of virtual environments and installations; mapping techniques using motion capture and 3D laser scanners; Buddhist philosophy and its relation to avatars and online environments; and experimental choreography. In 2013, Alan spoke at the South By Southwest Interactive festival on Glitch aesthetics and techniques.
The Internet Text can be seen as Sondheim's major work, and was included in the first . Posted online since 1994, it is both an aggregate of Sondheim's writings and a "continuous meditation on cyberspace." The works are distributed on several email lists and gathered on Sondheim's website. The significance of The Internet Text is as a document or residue of Sondheim diverse writings and performances, and also as a philosophical reflection on computer mediated communication and online culture.
