No, I don't know anything more that you. But I can contrast the scale of Twitter with other comparable, realtime, multi user sites like reddit and stackoverflow. Both of those sites have 230 and ~330 (I didn't count all the SO employees), respectively. And Stackoverflow is actually selling a product. Is Twitter so different from these sites? https://en.wikipedia.org/wiki/Reddit https://en.wikipedia.org/wiki/Reddit https://stackoverflow.com/company/team https://stackoverflow.com/company/team
