I just recently subscribed to DCM and am looking forward to learning and absorbing as much as i can from the magazine..
I bought a couple of copies previously that i felt helped me as a beginner and decided to subscribe..
I know that doesn't alleviate most of what is being said here...or help in anyway

however maybe if DCM editors do read their subscribers views this could help somewhat...
Does anyone remember the children magz that use to be upside downs half the magazine "beginner reader" was upright like you see all magz, the 'advanced reader was upside down" at the rear of the mag, and the other half of the magazine"
ideally it had kids to read the first half then if they felt confident theyd flip it over and read the more advanced worded stories etc..
I'm thinking if DCM or any photographic magazine for that matter wanted to continually keep their subscribers from beginner to advanced then maybe they need to do a version of the Upside down magz, or even back to backs make the magaazne bigger better and fulfill more then just beginners needs, without dumping those subscribers..
In everything I've done in my life, i really feel even with our advanced knowledge as we learn, that there will be at times beginner things we forget or that touch on something we hadnt seen before or in a different way adding a whole new concept for us to learn,etc... so keeping the beginner side of the magazine will benefit advanced users at times, but continue to keep in the tradition of teaching new hobbiest/professionals the world of photography... it means those new subscribers who are advancing will be able to go one further when confident enough and learn from the advanced section as will all advanced photographers, it would be 2 mediums in one holding onto a much larger subscriber base and keeping the subscriber interested in the magazine, rather then have them leave once they have gone beyond the scope and range of being a beginner..
my 2 cents..
