I don't know how well #posh worked for everybody else but for me it did very well. Not only that I got some nice upvotes from both @ocd and @ocdb, but I started interacting with some of my fellow steemians outside Steem as well. Twitter is my only mainstream social media platform and I feel good about sharing my posts there. Who knows who's gonna find out about Steem through my posts... Great initiative. Keep up with the good work!
