SI will remain most of all "experimental sound" magazine. Themes that are involved in music can be covered. There is new feature of books starting in SI #8. Meaning various artists (in this issue Sick Seed) talks about some essential book(s), what in some ways relate/influence their work or them as person. Be it fiction, non-fiction, text or image books, whatever. Future issues will have more.
However, to cover all sorts of "transgressive" issues without direct contact to sound-art is useless. There are (or has been) plenty of magazines, websites, and forums for sex, violence, conspiracy, cults, murderers, but very little for this side of experimental sound what SI covers.
Amount of coverage of literature or/and art related to noise may increase in future, but I hope it all comes from angle of experimental sound works.
