Honestly, my first opinion (and likely that of many others) was "how can you ask that question here?" However, asked honestly, and not to start some "us vs them" battle (as definitely seems the case), the answer to "how can you ask that question here?" should be "why not?" OGR certainly isn't going to lose any readership over it, and it allows many of their readers to express why it's THEIR choice. As someone else previously mentioned, many companies spend tons of dollars for this sort of insight into their customer base, and here it's being provided free of charge.
Different people get different things out of the hobby. What may be fascinating to one reader may be of no interest to another. Some folks just run out and buy whatever strikes their fancy from a manufacturer's new catalog, many of which may never see time out of their box, while others spend countless hours modifying things, building structures, wiring trackwork, etc... Some own nothing made this century, and delight in the ozone-laced air of their aged machines. Each takes away what THEY find enjoyable, and the hobby is big enough to encompass all of them.
Much good guidance has already been giving by others over what aspects of the hobby are covered more in-depth by each magazine, but Panico's Brick Oven Pizza in New Brunswick, NJ has both some excellent thin-crust pizza AND RC Cola on tap!
