What is a "general-interest" magazine? Outside of something so vanilla as National Geographic, Time, or Newsweek, I can't think of magazines that aren't market-segment sliced-and-diced. Computer parts and tech magazines might be inevitable detritus of any office/area focused on working with technology. Do I have to lockup my programming books and hide away the spare components I'm working with?
