Steemit blog announced it here...https://steemit.com/steemit/@steemitblog/join-team-steemit-at-tokenfest
London Cryptocurrency Show was big as well, I think also 2000+ attendance. But that one was mainly facilitated by #promo-steem team. By the way, this team is doing an amazing job promoting Steem. They may need support from investors like you who care about Steem.
