To those involved with the production of the 'zine: have you considered doing a companion podcast to accompany each issue? Similar idea to other zines doing an issue + CD (or tape or whatever), but instead using the new media of podcasting. It's always good to hear examples from the work of the artists being interviewed, plus you could also include audio interviews if the opportunity ever arises. I think podcasting makes this more of a reality now than in the past, because obviously it would be much cheaper than doing a run of tapes/CDs.
Who knows, maybe I'm alone. This kind of music, like other genres of underground music, is very dedicated to physical media and maybe what I'm suggesting wouldn't be accepted. I do think there would be an audience for it though. There are a few existing industrial/noise/p.e. podcasts out there (The Plague Cast comes to mind, great job btw), but they're very sporadic and perhaps a regular SI podcast would fill a void.
