"...doesn't mean a group/class of people..." I'm well aware of that, as well as the definition, however, i've come across incorrect usage of the term on SMS as the short form for "common man/common people". Considering the context of that persons comment, i was under assumption that they use that term incorrectly, hence why i've put it in quotation. Regardless, my point still stands. "The commons is the cultural and natural resources accessible to all members of a society, including natural materials such as air, water, and a habitable Earth. These resources are held in common even when owned privately or publicly. Commons can also be understood as natural resources that groups of people (communities, user groups) manage for individual and collective benefit.". Note that the definition provided by you acknowledges various form of ownerships (private vs public) and that aspect is the core of my response to that comment.
