The most helpful steemian I have encountered thus far has been @cryptkeeper17. This steemian has gone out of their way to promote some of my music from my blog, and has also taught me about bots and curation. Not only that, but I've seen that they help a bunch of other folks on steemit as well. See my "official recommendation" here ;) https://steemit.com/steembasicincome/@gjones15/name-a-helpful-steemian. Thanks, @cryptkeeper17!
