Welcome to 2013. Before we completely put the shackles on 2012, I thought you'd be interested in knowing which Design News articles garnered the most interest in 2012.
I'm judging interest using two different measuring sticks. First, you'll find the five most read articles of the year. (I'm assuming that, if you clicked on the article, you actually read it.) The second list is the five articles that drew the most comments. These are the pieces that generated reactions strong enough for readers to leave an observation.
It's nice to see readers interested in articles interested in issues that affect the environment, like global warming and hybrid cars. I'm expecting the environment and ways engineers and designers can improve energy efficiency in products as well as be more environmentally friendly in general to continue to be hot issues in 2013.
Richard, if we are going through the list it seems that Communication and Automobiles are more interested topics to our readers and environmental issues are the concerns, where most of them commented. I think this type of analysis will help you to plan which are the topics more interested to our community members.
