since most view are external.. i think it means that medium isn't circulating it, yet it most likely is getting some good seo on google instead.. but most likely medium will start to circulate it internally and then hopefully it picks up more steam and gets more intenral views.. I am not sure tho.. I have had two semi viral, i don't know the definition of viral either, but they picked up steam for a day then dropped, and then a few days later took off in medium.. sooo you never know, but congrats that was a good article..
