I just recently joined Facebook exclusively to participate in some maker groups. I'm a little surprised, maybe put off, by how many people's profile pic include what I assume to be their spouse/partner/sigOther. Is this a thing? This strikes me as odd, particularly since my interest there is not social. Is this code for "I'm taken" or more like people putting their brand on their Facebook-faring partner so everyone knows to keep the f*** away???
