“It’s in this kind of context that we should look at the labor we put into social media. Twitter is work, Facebook is work. Words are being written, content produced and shared, ads sold against it. A welter of data, some of it structured by us, is produced, and this has value. Yes, this work is often voluntary. You put in what you want, and if you don’t like that Facebook is profiting off of your relationships and communication with friends and your very identity, then you can quit.”
