The Best of the Web for Engineers

Social media is a hot topic these days, even among engineers. Here are some of the most interesting and useful engineering-related Twitter feeds, blogs, forums, and LinkedIn groups that Machine Design editors have come across in the past year. We also note Web sites devoted to 3D printing/manufacturing that we felt are worth a look.
