huh? Isn't this an 'old' thing from within communication/psychology? I spent quite some time with my therapist in 97/98 discussing why I purposefully avoided context collapse as a kid preventing different circles from overlapping. 2010 is the ref'd paper, I use it in my blog in May 2009 https://www.zylstra.org/blog/2009/05/hate_mailers_un/ (though I may have been aware of boyd or Michael Wesch using it then). Wikipedia https://en.wikipedia.org/wiki/Context_collapse says boyd is credited with coining 'collapsed contexts' (which is both a hedge by WP editors and different from the claim here). Did she already use it when I first encountered her (work) in 2006 during her Phd?
