I was thinking about the metaphor you used in responding to my question, that “social media are like new languages”, then after reflecting on that idea for a while I re-read your response and realized that you had actually said “social media are new languages” not like new languages, they are actually new language

I think learning how to work in, and be in, social networks as an adult, in a workplace context, is very similar to the process of learning to function effectively in a second or additional language.
