cheating the polygraph
I wonder how much traffic an online zine of this nature would actually get. As great as this could be, I'm not holding my breath. Add in that it's hard enough to find reviewers that describe music well or that you can at least figure out whether or not you'd enjoy the music based on their opinions, and this zine becomes even more unlikely.
I have to agree that this would better be served as a webpage or blog with a similar format to the recommendation threads (with or without the mp3s, offsite links such as myspace would be a better option here) than a full-fledged zine...just put "no promos or CD-Rs accepted" in small print.
