Yes, we have a team of Steem Ambassadors (anyone can be one, as long as they make a blog to per the application process shown on the website and the @steem-ambassador blog and the community accepts them) they help curate the promo steem tag and then we use our steem power to upvote amazing promotional content. We also have a voting trail at steemauto Under @steem-ambassador. We have on average 50 people posting to the tag #promo-steem each day. Check it out to see what everyone is doing!!
