to your, you know -- example of this, in the forthcoming book, #activism, which i coauthored with moya bay lee and wells, we look at #activism, and one of the things that is interesting is everyone has heard at this point of me too -- of the hash tag me too. and even hash tag me too, there were some, you know, questions around its creation and ownership that had to do with race. particularly because there was an organization called me too and was initially not given credit for the phrasing, but that was corrected and very quickly corrected, because black women on the internet said, hey, this is -- you need to interrogate where credit is being given here. but that said, we are argue in the book that me too is made possible by other hash tags that are sort of less well-known that are as the doctor mentioned sometimes in less visible and yet they start to essentially -- are the building blocks towards visibility. and so we look at -- there's four hash tags in particular that we found were especially influential on twitter that didn't get the same type of mainstream attention offline as me
